Ensure that the unused fields are explicitly stated when defining the types.
Add some compile time assertions about the size requirements for the structure
types.

name_ids() did not return all IDs but only the first NameCount items.
The number of non-zero entries in IDs vector is NameCount, but it
does not mean that all non-zero entries are at the beginning of IDs
vector.

This is a support COFF feature. Ensure that we can display the weak externals
auxiliary symbol. It contains useful information (such as the default binding
and how to resolve the symbol).

[AMDGPU] emitPrologue looks for an unused unallocated SGPR that is not
the scratch descriptor. Continue search if unused register found fails
other requirements.

We have to modify V2SU before inserting new elements into the
CurrentVRegDefs set because that may move V2SU in memory invalidating
the reference.

Summary:
Adds fastpath instrumentation for esan's working set tool. The
instrumentation for an intra-cache-line load or store consists of an
inlined write to shadow memory bits for the corresponding cache line.
Adds a basic test for this instrumentation.

This patch adds support for:
S_EXPORT
LF_BITFIELD
With this patch, I have run through a couple of gigabytes of PDB
files and cannot find a type or symbol that we do not understand.

Instead of this:
i32.const $push10=, __stack_pointer
i32.load $push11=, 0($pop10)
Emit this:
i32.const $push10=, 0
i32.load $push11=, __stack_pointer($pop10)
It's not currently clear which is better, though there's a chance the second
form may be better at overall compression. We can revisit this when we have
more data; for now it makes sense to make PEI consistent with isel.

This adds support for parsing and dumping the following
symbol types:
S_LPROCREF
S_ENVBLOCK
S_COMPILE2
S_REGISTER
S_COFFGROUP
S_SECTION
S_THUNK32
S_TRAMPOLINE
As of this patch, the test PDB files no longer have any unknown
symbol types.

Summary:
Adds createEsanInitToolGV for creating a tool-specific variable passed
to the runtime library.
Adds dtor "esan.module_dtor" and inserts calls from the dtor to
"__esan_exit" in the runtime library.
Updates the EfficiencySanitizer test.

The benefits of this patch are
-- We call AnalyzeBranch() to optimize unanalyzable branches, but the result of
AnalyzeBranch() is not used. Now the result is useful.
-- Before the layout of all the MBBs is set, the result of AnalyzeBranch() is
not correct and needs to be fixed before using it to optimize the branch
conditions. Now this optimization is called after the layout, the code used
to fix the result of AnalyzeBranch() is not needed.
-- The branch condition of the last block is not optimized before. Now it is
optimized.

These attributes aren't used by other debuggers (& may be confused with
other DWARF extensions) so they just waste space (about 1.5% on .dwo
file size on a random large program I tested).
We could remove the ObjC property ones too, but I figured they were
probably more necessary when trying to understand ObjC (I could be wrong
though) & so any debugger interested in working with ObjC would use
them, perhaps? (also, there are some legacy tests in Clang that test for
them - making it one of those annoying cross-project commits and/or
cleanup to refactor those tests)

When dumping huge PDB files, too many of the options were grouped
together so you would get neverending spew of output. This patch
introduces more granular display options so you can only dump the
fields you actually care about.

This should fix PR27855. We have some terrible hacks in the CMake to add linking SYSTEM_LIBS to all tools. I think we need a better way to do this in the future.

This makes use of the newly introduced `CVSymbolVisitor` to dump details
of each type of symbol record in the symbol streams. Future patches will
bring this visitor based dumping to the publics stream, as well as
creating a `SymbolDumpDelegate` to print more information about
relocations etc.

Summary:
This patch changes the ODR resolution and internalization to be based on
updates to the Index, which are consumed by the backend portion of the
transformations.
It will be followed by an NFC change to move these out of libLTO's
ThinLTOCodeGenerator so that it can be used by other linkers
(gold and lld) and by ThinLTO distributed backends.
The global summary-based portions use callbacks so that the client can
determine the prevailing copy and other information in a client-specific
way. Eventually, with the API being developed in D20268, these may be
modified to use information such as symbol resolutions, supplied by the
clients to the API.
