Frederic Riss e837ec29c3 Reapply "[dwarfdump] Add support for dumping accelerator tables."
This reverts commit r221842 which was a revert of r221836 and of the
test parts of r221837.

This new version fixes an UB bug pointed out by David (along with
addressing some other review comments), makes some dumping more
resilient to broken input data and forces the accelerator tables
to be dumped in the tests where we use them (this decision is
platform specific otherwise).

Jay Foad 1180c05db2 [ASan] Improved stack overflow detection for PowerPC64
Summary:
AsanOnSIGSEGV has some heuristics for detecting stack overflow, but
they don't cope with a PowerPC store-with-update instruction which
modifies sp and stores to the modified address in one instruction.

This patch adds some PowerPC-specific code to check for this case.

This fixes the last few cases of the stack-overflow test.

Bill Schmidt 8ff672d397 [PowerPC] Enable vec_perm for long long and double vector types for VSX
VSX makes the "vector long long" and "vector double" types available.
This patch enables the vec_perm interface for these types.  The same
builtin is generated regardless of the specified type, so no
additional work or testing is needed in the back end.  Tests are added
to ensure this builtin is generated by the front end.

This patch adds builtin support for xvdivdp and xvdivsp, along with a
new test case.  The builtins are accessed using vec_div in altivec.h.
Builtins are listed (mostly) alphabetically there, so inserting these

test/Headers/altivec-intrin.c.

There is a companion patch for LLVM.

David Majnemer f69b0585c1 obj2yaml, yaml2obj: Add support for COFF executables
In support of serializing executables, obj2yaml now records the virtual address
and size of sections.  It also serializes whatever we strictly need from
the PE header, it expects that it can reconstitute everything else via
inference.

yaml2obj can reconstitute a fully linked executable.

In order to get executables correctly serialized/deserialized, other
bugs were fixed as a circumstance.  We now properly respect file and
section alignments.  We also avoid writing out string tables unless they
are strictly necessary.

Alexey Bataev 9aba41c822 [OPENMP] Temporary fix for processing of global variables in loops.
Currently there is a bug in processing of global variables used as loop control variables in 'omp for/simd' constructs: these globals must be captured as private variables, but currently they are nor. This is a temporary bug fix for this problem until the correct solution is prepared. If a global var used as lcv without explicit mark as a private/linear/lastprivate the error message is emitted.

Eric Fiselier 950a166710 Split string capacity test into two parts and mark one part as UNSUPPORTED when using sanitizers.
The test is split such that:
- max_size.pass.cpp tests that string::resize() fails to allocator for max_size
  and max_size -1
- over_max_size.pass.cpp tests that string::resize() throws a length error for
  max_size + 1

The test was split into two because max_size.pass.cpp cannot pass with 
sanitizers but over_max_size.pass.cpp can.

Eric Fiselier eb2378b70c Mark more tests as UNSUPPORTED with ASAN and MSAN.
These tests fail for 2 reasons when using ASAN and MSAN.
1. If allocator_may_return_null=0 they will fail because null is returned
   or an exception is thrown.
2. When allocator_may_return_null=1 the new_handler is still not called. This
   results in an assertion failures.
