This adds the following values to the CodeView.h enums (and updates the
various functions that use them):
* CPUType:
* Added `Unknown`
* This is not currently documented in the online documentation, but this
is present in `cvconst.h` in the latest DIA SDK (Visual Studio 2022,
17.7.6)
* `Unknown` is the CPUType that is emitted by `aliasobj.exe` in the
Compile3Sym records, and can be found in objects that link with
`oldnames.lib`
* SourceLanguage (All of these are documented at
https://learn.microsoft.com/en-us/visualstudio/debugger/debug-interface-access/cv-cfl-lang?view=vs-2022
and are present in `cvconst.h` in the latest DIA SDK (Visual Studio
2022, 17.7.6))
* Added Go
* Added AliasObj
* emitted by `aliasobj.exe` in certain records, can be found in PDBs
that link with `oldnames.lib`
* Changed Swift to the official Microsoft enumeration
* Added `OldSwift`
* The old Swift enumeration of `S` was changed to `OldSwift` to allow
pdb dumping utilities to continue to emit correct source language
information for old PDBs
### WARNING
The `Swift` change is a potentially breaking change, as the swift
compiler will now emit `0x13` for the SourceLanguage type in PDB records
instead of `S`. This could potentially break utilities that relied on
the old enum value.
* CallType
* Added Swift
* This is not currently documented in the online documentation, but this
is present in `cvconst.h` in the latest DIA SDK (Visual Studio 2022,
17.7.6)

This patch adds llvm::codeview::SourceLanguage entries, DWARF translations, and PDB source file extensions in LLVM and allow LLDB's PDB parsers to recognize them correctly.
The CV_CFL_LANG enum in the Visual Studio 2022 documentation https://learn.microsoft.com/en-us/visualstudio/debugger/debug-interface-access/cv-cfl-lang defines:
```
CV_CFL_OBJC = 0x11,
CV_CFL_OBJCXX = 0x12,
```
Since the initial commit in D24317, ObjC was emitted as C language and ObjC++ as Masm.

Microsoft has added several new entries to the CV_CFL_LANG enum, including Rust:
https://docs.microsoft.com/en-us/visualstudio/debugger/debug-interface-access/cv-cfl-lang
This change adds Rust to the corresponding LLVM enum and translates `dwarf::DW_LANG_Rust` to `SourceLanguage::Rust` in the CodeView AsmPrinter.
This means that Rust will no longer emit as Masm.

handling
- getCompression() used to return a PDB_SourceCompression even though
the docs for IDiaInjectedSource are explicit about the return value
being compiler-dependent. Return an uint32_t instead, and make the
printing code handle unknown values better by printing "Unknown" and
the int value instead of not printing any compression.
- Print compressed contents as hex dump, not as string.
- Add compression type "DotNet", which is used (at least) by csc.exe,
the C# compiler. Also add a lengthy comment describing the stream
contents (derived from looking at the raw hex contents long enough
to see the GUIDs, which led me to the roslyn and mono implementations
for handling this).
- The native injected source dumper was dumping the contents of the
whole data stream -- but csc.exe writes a stream that's padded with
zero bytes to the next 512 boundary, and the dia api doesn't display
those padding bytes. So make NativeInjectedSource::getCode() do the
same thing.

CodeView has its own register map which is defined in cvconst.h. Missing this
mapping before saving register to CodeView causes debugger to show incorrect
value for all register based variables, like variables in register and local
variables addressed by register (stack pointer + offset).
This change added mapping between LLVM register and CodeView register so the
correct register number will be stored to CodeView/PDB, it aso fixed the
mapping from CodeView register number to register name based on current
CPUType but print PDB to yaml still assumes X86 CPU and needs to be fixed.

Summary:
Swift now generates PDBs for debugging on Windows. llvm and lldb
need a language enumerator value too properly handle the output

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Previously we would dump the names of enum types, but not their
enumerator values. This adds support for enumerator values. In
doing so, we have to introduce a general purpose mechanism for
caching symbol indices of field list members. Unlike global
types, FieldList members do not have a TypeIndex. So instead,
we identify them by the pair {TypeIndexOfFieldList, IndexInFieldList}.

The missing definitions are from cvconst.h shipped with DIA SDK.

Injected sources are basically a way to add actual source file content
to your PDB. Presumably you could use this for shipping your source code
with your debug information, but in practice I can only find this being
used for embedding natvis files inside of PDBs.
In order to effectively test LLVM's natvis file injection, we need a way
to dump the injected sources of a PDB in a way that is authoritative
(i.e. based on Microsoft's understanding of the PDB format, and not
LLVM's). To this end, I've added support for dumping injected sources
via DIA. I made a PDB file that used the /natvis option to generate a
test case.

The list of register ids was previously written out in a couple of dirrent
places. This puts it in a .def file and also adds a few more registers (e.g.
the x87 regs) which should lead to more readable dumps, but I didn't include
the whole list since that seems unnecessary.
X86_MC::initLLVMToSEHAndCVRegMapping is pretty ugly, but at least it's not
relying on magic constants anymore. The TODO of using tablegen still stands.

Summary:
We were treating the GUIDs in TypeServer2Record as strings, and the
non-ASCII bytes in the GUID would not round-trip through YAML.
We already had the PDB_UniqueId type portably represent a Windows GUID,
but we need to hoist that up to the DebugInfo/CodeView library so that
we can use it in the TypeServer2Record as well as in PDB parsing code.

The DBI stream contains a lot of bookkeeping information for other
streams. In particular it contains information about section contributions
and linked modules. This patch is a first attempt at parsing some of the
information out of the DBI stream. It currently only parses and dumps the
headers of the DBI stream, so none of the module data or section
contribution data is pulled out.
This is just a proof of concept that we understand the basic properties of
the DBI stream's metadata, and followup patches will try to extract more
detailed information out.

The IDiaSymbol::getValue() method returns a variant. Until now,
I had never encountered a string value, so the Variant wrapper
did not support VT_BSTR. Now we have need to support string

This rewrites and expands the existing codeview dumping functionality in
llvm-readobj using techniques similar to those in lib/Object. This defines a
number of new records and enums useful for reading memory mapped codeview
sections in COFF objects.
The dumper is intended as a testing tool for LLVM as it grows more codeview
output capabilities.

This will now display enum definitions both at the global
scope as well as nested inside of classes. Additionally,
it will no longer display enums at the global scope if the
enum is nested. Instead, it will omit the definition of
the enum globally and instead emit it in the corresponding
class definition.

A short list of some of the improvements:
1) Now supports -all command line argument, which implies many
other command line arguments to simplify usage.
2) Now supports -no-compiler-generated command line argument to
exclude compiler generated types.
3) Prints base class list.
4) -class-definitions implies -types.
5) Proper display of bitfields.
6) Can now distinguish between struct/class/interface/union.
And a few other minor tweaks.

Function pointers were not correctly handled by the dumper, and
they would print as "* name". They now print as
"int (__cdecl *name)(int arg1, int arg2)" as they should.
Also, doubles were being printed as floats. This fixes that bug
as well, and adds tests for all builtin types. as well as a test
for function pointers.

This increases the flexibility of how to dump different
symbol types -- necessary for context-sensitive formatting of
symbol types -- and also improves the modularity by allowing
the dumping to be implemented in the actual dumper, as opposed
to in the PDB library.

This patch adds a number of improvements to llvm-pdbdump.
1) Dumping of the entire global scope, and not only those
symbols that live in individual compilands.
2) Prepend class name to member functions and data

4) Support for dumping more kinds of data symbols.

Frequently you only want to iterate over children of a specific
type (e.g. functions). Previously you would get back a generic
interface that allowed iteration over the base symbol type,
which you would have to dyn_cast<> each one of. With this patch,
we allow the user to specify the concrete type as a template
parameter, and it will return an iterator which returns instances
of the concrete type directly.

This makes llvm-pdbdump available on all platforms, although it
will currently fail to create a dumper if there is no PDB reader
implementation for the current platform.
It implements dumping of compilands and children, which is less
information than was previously available, but it has to be
rewritten from scratch using the new set of interfaces, so the
rest of the functionality will be added back in subsequent commits.
