David Majnemer c10b8381f7 Update tests touched by r249656
These test updates almost exclusively around the change in behavior
around enum: enums without a definition are considered incomplete except
when targeting MSVC ABIs.  Since these tests are interested in the
'incomplete-enum' behavior, restrict them to %itanium_abi_triple.

David Majnemer 3f02150d31 [MSVC Compat] Enable ABI impacting non-conforming behavior independently of -fms-compatibility
No ABI for C++ currently makes it possible to implement the standard
100% perfectly.  We wrongly hid some of our compatible behavior behind
-fms-compatibility instead of tying it to the compiler ABI.

Douglas Katzman 3459ce2e5e Stop messing with the 'g' group of options in CompilerInvocation.
With this change, most 'g' options are rejected by CompilerInvocation.
They remain only as Driver options. The new way to request debug info
from cc1 is with "-debug-info-kind={line-tables-only|limited|standalone}"
and "-dwarf-version={2|3|4}". In the absence of a command-line option
to specify Dwarf version, the Toolchain decides it, rather than placing
Toolchain-specific logic in CompilerInvocation.

Also fix a bug in the Windows compatibility argument parsing
in which the "rightmost argument wins" principle failed.

Diego Novillo b7fca57493 Handle inline stacks in gcov-encoded sample profiles.
This patch adds support for reading sample profiles with inline stacks.
Inline stacks in a profile are generated when the sampled binary has
samples in inlined functions.

For instance, if main() calls foo() and foo() calls bar(), and bar() is
inlined into foo() and foo() inlined into main(), the profile may look
something like:

main total:364084 head:0
  [ ... ]
  2.3: _Z3fool total:243786
    1: 60149
    1.2: 38568
    1.4: 46511
    1.7: _Z3bari total:98558
      1.1: 52672
      1.2: 45886

At line 2, discriminator 3, main() calls foo(). In turn, foo() calls
bar() at line 1, discriminator 7.

In the textual format, this stacking of inline calls is represented
with indentation.

With this change, LLVM can now read sample profile files generated by
the create_gcov tool from https://github.com/google/autofdo.

Justin Bogner 468c998031 CodeGen: print and verify after TargetPassConfig::insertPass by default
In r224059, we started verifying after addPass, but missed doing so on
insertPass. There isn't a good reason for the discrepancy, and
skipping the verifier in these cases causes bugs.

This also exposes a verifier error that was introduced in r249087, but
the verifier doesn't run until after the register coalescer, when the
issue happens to have been resolved. I've skipped the verifier after
SIFixSGPRLiveRangesID to avoid the failures for now and will follow up
with Matt for a proper fix.

Right now clang_Cursor_getMangling will attempt to mangle any
declaration, even if the declaration isn't mangled (extern C).  This
results in a partially mangled name which isn't useful for much. This
patch makes clang_Cursor_getMangling return an empty string if the
declaration isn't mangled.

Alexey Samsonov d9cc7f884f Provide missing Internal{Alloc, Free} declarations for libbacktrace symbolizer.
Summary:
Since r223145 we don't include sanitizer_allocator_internal.h into
sanitizer_symbolizer.h, so we can have undefined reference to
Internal{Alloc, Free} stuff into sanitizer_symbolizer_libbacktrace.cc under
SANITIZER_CP_DEMANGLE macro.

This patch simply includes appropriate header into
sanitizer_symbolizer_libbacktrace.h to resolve the issue.

Pete Cooper e11c9de83d Stop linking all target libraries in llvm-nm and llvm-objdump.
llvm-nm only needs the target to parse module level assembly in bitcode.  It doesn't need a disassembler or codegen.

llvm-objdump needs to be able to disassemble a file, but doesn't need asm parsers or codegen.

This reduces the sizes of these tools by a few MB each, depending on how many backends are linked in.

Greg Clayton db2a576a77 Don't do DWO tests on darwin as they aren't supported. If this is an error and they are supported, we need to add support _only_ if the clang compiler that is being used supports the compiler option for DWO stuff as right now I just get an error saying "warning: unused option -gsplit-dwarf". So unless we can successfully test if "-gsplit-dwarf" is truly supported, I am going to disable it on darwin for now so we don't get test suite failures.

The __CxxFrameHandler3 tables for 32-bit are supposed to hold stack
