Specifically:
- Start using %expect_crash.
- Provide an implementation of __ubsan::getDynamicTypeInfoFromVtable
for the Microsoft C++ ABI. This is all that is needed for CFI
diagnostics; UBSan's -fsanitize=vptr also requires an implementation of
__ubsan::checkDynamicType.
- Build the sanitizer runtimes against the release version of the C
runtime, even in debug builds.
- Accommodate demangling differences in tests.

Place all code corresponding to a run-time check in one place.
Previously we generated some code, then proceeded to a next check, then
finished the code for the first check (like splitting blocks and
generating branches). Now the code for generating a check is
self-contained.

There are known issues, but the current implementation is good enough for
the check-cfi test suite.

All the usual X86 target-specific conventions are collapsed to the
normal Win64 convention, but the custom conventions like GHC and webkit
should not be.
Previously we would assume that the caller allocated 32 bytes of shadow
space for us, which is not how webkit_jscc or other custom conventions
are supposed to work.
Based on a patch by peavo@outlook.com.
Fixes PR24051.

No support for the symbol table yet (but will hopefully add it today).
We always use the long filename format so that we can align the member,
which is an advantage of the BSD format.

Symbols exported by DLLs are listed in import library files.
Exported names may be mangled by "Import Name Type" field as
described in PE/COFF spec 7.3. This patch implements that
mangling scheme.

This commit changes the type of the field 'Name' in the struct
'yaml::MachineBasicBlock' from 'std::string' to 'yaml::StringValue'. This change
allows the MIR parser to report errors related to the MBB name with the proper
source locations.

Summary:
This is used on non-unix platforms, where qXfer:libraries-svr4:read
doesn't make sense. Windows uses that for instance.

The inferred output file name is based on the first input file, not the
first one with extension .obj. The output file was also being written to
the wrong directory; it needs to be written to whichever directory on the
libpath it was found in. This change fixes both issues.

Until somebody writes the code for it, be loud about the fact that
it's not implemented yet.

r239285 ([LoopAccessAnalysis] Teach LAA to check the memory dependence
between strided accesses.) introduced a new case under
MemoryDepChecker::isDependent. We normally have debug output for each
case.

Desugar doesn't necessarily initialize ShouldAKA, but as of r241542 it
may read it. Fix the misuse of the API and initialize this before
passing it in.

The 32-bit lowering assumed that WinEHPrepare had this invariant.
WinEHPrepare did it for C++, but not SEH. The result was that we would
insert calls to llvm.x86.seh.restoreframe in normal basic blocks, which
corrupted the frame pointer.
