This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.
This doesn't actually modify StringRef yet, I'll do that in a follow-up.

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.

These work a little differently because they are actually in
the globals stream and are treated as symbol records, even though
DIA presents them as types. So this also adds the necessary
infrastructure to cache records that live somewhere other than
the TPI stream as well.

This allows them to be returned from the native API.

This adds support for parsing function signature records and returning
them through the native DIA interface.

This allows the native reader to find records of class/struct/
union type and dump them. This behavior is tested by using the
diadump subcommand against golden output produced by actual DIA
SDK on the same PDB file, and again using pretty -native to
confirm that we actually dump the classes. We don't find class
members or anything like that yet, for now it's just the class
itself.

These are dead code and encourage poor usage patterns, so I'm
removing them. They weren't called anywhere anyway.

In order to start testing this, I've added a new mode to
llvm-pdbutil which is only really useful for writing tests.
It just dumps the value of raw fields in record format.
This isn't really ideal and it won't allow us to test some
important cases, but it's better than nothing for now.

Part of the responsibility of the native PDB reader is to cache
symbols the first time they are accessed, so they can then be
looked up by an ID. Furthermore, we need to resolve type indices
to records that we vend to the user, and other things. Previously
this code was all thrown together a bit haphazardly in the native
session class, but it makes sense to collect all of this into a
single class whose sole responsibility is to manage the collection
of known symbols.
llvm-svn: 341608

The way DIA SDK works is that when you request a symbol, it
gets assigned an internal identifier that is unique for the
life of the session. You can then use this identifier to
get back the same symbol, with all of the same internal state
that it had before, even if you "destroyed" the original
copy of the object you had.
This didn't work properly in our native implementation, and
if you destroyed an object for a particular symbol, then
requested the same symbol again, it would get assigned a new
ID and you'd get a fresh copy of the object. In order to fix
this some refactoring had to happen to properly reuse cached
objects. Some unittests are added to verify that symbol
reuse is taking place, making use of the new unittest input
feature.

This extends the native reader to enable llvm-pdbutil to list the enums in a
PDB and it includes a simple test. It does not yet list the values in the
enumerations, which requires an actual implementation of
NativeEnumSymbol::FindChildren.
To exercise this code, use a command like:
llvm-pdbutil pretty -native -enums foo.pdb

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.

Summary:
There is a reserved range of type indexes for built-in types (like integers).
This will create a symbol for a built-in type if the caller askes for one by
type index. This is also plumbing for being able to recall symbols by type
index in general, but user-defined types will come in subsequent patches.

All NativeRawSymbols will have a unique symbol ID (retrievable via
getSymIndexId). For now, these are initialized to 0, but soon the
NativeSession will be responsible for creating the raw symbols, and it will
assign unique IDs.
The symbol cache in the NativeSession will also require the ability to clone
raw symbols, so I've provided implementations for that as well.

I tried to run llvm-pdbdump on a very large (~1.5GB) PDB to
try and identify show-stopping performance problems. This
patch addresses the first such problem.
When loading the DBI stream, before anyone has even tried to
access a single record, we build an in memory map of every
source file for every module. In the particular PDB I was
using, this was over 85 million files. Specifically, the
complexity is O(m*n) where m is the number of modules and
n is the average number of source files (including headers)
per module.
The whole reason for doing this was so that we could have
constant time access to any module and any of its source
file lists. However, we can still get O(1) access to the
source file list for a given module with a simple O(m)
precomputation, and access to the list of modules is
already O(1) anyway.
So this patches reduces the O(m*n) up-front precomputation
to an O(m) one, where n is ~6,500 and n*m is about 85 million
in my pathological test case.

This should work on all platforms now that r299006 has landed. Tested locally
on Windows and Linux.
This moves exe symbol-specific method implementations out of NativeRawSymbol
into a concrete subclass. Also adds implementations for hasCTypes and
hasPrivateSymbols and a simple test to ensure the native reader can access the
summary information for the executable from the PDB.

Reverting until I can figure out the root cause.
Revert "Re-land: Make NativeExeSymbol a concrete subclass of NativeRawSymbol [PDB]"

The new test should pass on all platforms now that llvm-pdbdump has the
`-color-output` option.

For some reason this is causing ANSI color codes to be printed
even when run through FileCheck.
