Update all uses of variadic `.Cases` to use the initializer list
overload instead. I plan to mark variadic `.Cases` as deprecated in a
followup PR.
For more context, see https://github.com/llvm/llvm-project/pull/163117.

Uses of (void) remain where they are for purposes other than an
assert variable.

Add MSP430 to the list of available targets, implement MSP430 ABI, add support for debugging targets with 16-bit address size.
The update is intended for use with MSPDebug, a GDB server implementation for MSP430.

This patch replaces (llvm::|)Optional< with std::optional<. I'll post
a separate patch to clean up the "using" declarations, #include
"llvm/ADT/Optional.h", etc.
This is part of an effort to migrate from llvm::Optional to
std::optional:

This patch mechanically replaces None with std::nullopt where the
compiler would warn if None were deprecated. The intent is to reduce
the amount of manual work required in migrating from Optional to
std::optional.

Previously, depending on how you constructed a UUID from data or a
StringRef, an input value of all zeros was valid (e.g. setFromData)
or not (e.g. setFromOptionalData). Since there was no way to tell
which interpretation to use, it was done somewhat inconsistently.
This standardizes the meaning of a UUID of all zeros to Not Valid,
and removes all the Optional methods and their uses, as well as the
static factories that supported them.

Since C++17 the message string for static_assert is optional. Replaces
static asserts with an empty string literal with the single-argument
variant.

breakpad.
Teach LLDB to understand INLINE and INLINE_ORIGIN records in breakpad.
They have the following formats:
```
INLINE inline_nest_level call_site_line call_site_file_num origin_num [address size]+
INLINE_ORIGIN origin_num name
```
`INLNIE_ORIGIN` is simply a string pool for INLINE so that we won't have
duplicated names for inlined functions and can show up anywhere in the symbol
file.
`INLINE` follows immediately after `FUNC` represents the ranges of momery
address that has functions inlined inside the function.

SBTarget::AddModule currently handles the UUID parameter in a very
weird way: UUIDs with more than 16 bytes are trimmed to 16 bytes. On
the other hand, shorter-than-16-bytes UUIDs are completely ignored. In
this patch, we change the parsing code to handle UUIDs of arbitrary
size.
To support arbitrary size UUIDs in SBTarget::AddModule, this patch
changes UUID::SetFromStringRef to parse UUIDs of arbitrary length. We
subtly change the semantics of SetFromStringRef - SetFromStringRef now
only succeeds if the entire input is consumed to prevent some
prefix-parsing confusion. This is up for discussion, but I believe
this is more consistent - we always return false for invalid UUIDs
rather than sometimes truncating to a valid prefix. Also, all the
call-sites except the API and interpreter seem to expect to consume
the entire input.
This also adds tests for adding existing modules 4-, 16-, and 20-byte
build-ids. Finally, we took the liberty of testing the minidump
scenario we care about - removing placeholder module from minidump and
replacing it with the real module.

Summary:
A *.cpp file header in LLDB (and in LLDB) should like this:
```
//===-- TestUtilities.cpp -------------------------------------------------===//
```
However in LLDB most of our source files have arbitrary changes to this format and
these changes are spreading through LLDB as folks usually just use the existing
source files as templates for their new files (most notably the unnecessary
editor language indicator `-*- C++ -*-` is spreading and in every review
someone is pointing out that this is wrong, resulting in people pointing out that this
is done in the same way in other files).
This patch removes most of these inconsistencies including the editor language indicators,
all the different missing/additional '-' characters, files that center the file name, missing
trailing `===//` (mostly caused by clang-format breaking the line).

D59433 and D60501 changed the way UUIDs are computed from minidump
files. This was done to synchronize the U(G)UID representation with the
native tools of given platforms, but it created a mismatch between
minidumps and breakpad files.
This updates the breakpad algorithm to match the one found in minidumps,
and also adds a couple of tests which should fail if these two ever get
out of sync. Incidentally, this means that the module id in the breakpad
files is almost identical to our notion of UUIDs, so the computation
algorithm can be somewhat simplified.

Summary:
This patch adds support for parsing STACK CFI records from breakpad
files. The expressions specifying the values of registers are not
parsed.The idea is that these will be handed off to the postfix
expression -> dwarf compiler, once it is extracted from the internals of
the NativePDB plugin.

Previously we would classify all STACK records into a single bucket.
This is not really helpful, because there are three distinct types of
records beginning with the token "STACK" (STACK CFI INIT, STACK CFI,
STACK WIN). To be consistent with how we're treating other records, we
should classify these as three different record types.
It also implements the logic to put "STACK CFI INIT" and "STACK CFI"
records into the same "section" of the breakpad file, as they are meant
to be read together (similar to how FUNC and LINE records are treated).
The code which performs actual parsing of these records will come in a
separate patch.

The two records aren't used by anything yet, but this part can be
separated out easily, so I am comitting it separately to simplify
reviews of the followup patch.

Summary:
This addresses the issues raised in D56844. It removes the accessors from the
breakpad record structures by making the fields public. Also, I refactor the
UUID parsing code to remove hard-coded constants.

This patch extends SymbolFileBreakpad::AddSymbols to include the symbols
from the FUNC records too. These symbols come from the debug info and
have a size associated with them, so they are given preference in case
there is a PUBLIC record for the same address.
To achieve this, I first pre-process the symbols into a temporary
DenseMap, and then insert the uniqued symbols into the module's symtab.

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.

Summary:
This centralizes parsing of breakpad records, which was previously
spread out over ObjectFileBreakpad and SymbolFileBreakpad.
For each record type X there is a separate breakpad::XRecord class, and
an associated parse function. The classes just store the information in
the breakpad records in a more accessible form. It is up to the users to
determine what to do with that data.
This separation also made it possible to write some targeted tests for
the parsing code, which was previously unaccessible, so I write a couple
of those too.
