Unify the two CRC implementations
David added the JamCRC implementation in r246590. More recently, Eugene 
added a CRC-32 implementation in r357901, which falls back to zlib's 
crc32 function if present.
These checksums are essentially the same, so having multiple 
implementations seems unnecessary. This replaces the CRC-32 
implementation with the simpler one from JamCRC, and implements the 
JamCRC interface in terms of CRC-32 since this means it can use zlib's 
implementation when available, saving a few bytes and potentially making 
it faster.
JamCRC took an ArrayRef<char> argument, and CRC-32 took a StringRef. 
This patch changes it to ArrayRef<uint8_t> which I think is the best 
choice, and simplifies a few of the callers nicely.

[llvm-exegesis] Add missing std::move in rL374146.
This was breaking some bots:

[TableGen] Fix crash when using HwModes in CodeEmitterGen
When an instruction has an encoding definition for only a subset of the
available HwModes, ensure we just avoid generating an encoding rather
than crash.

Revert r374006: Reland 'Add VFS support for sanitizers' blacklist'
Also revert follow-up changes to the test. Reason: the patch breaks our
internal clang-tidy integration.
It's also unclear why we should use getRealPath instead of plumbing the 
VFS to SanitizerBlacklist, see original commit thread of cfe-commits for 
a discussion.

[Sema] Emit diagnostics for uncorrected delayed typos at the end of TU
Summary: Instead of asserting all typos are corrected in the sema
destructor.
The sema destructor is not run in the common case of running the
compiler with the -disable-free cc1 flag (which is the default in the
driver).
Having this assertion led to crashes in libclang and clangd, which are
not reproducible when running the compiler.
Asserting at the end of the TU could be an option, but finding all 
missing typo correction cases is hard and having worse diagnostics
instead of a failing assertion is a better trade-off.

[DebugInfo] Enable call site debug info for ARM and AArch64
ARM and AArch64 SelectionDAG support for tacking parameter forwarding 
register is implemented so we can allow clang invocations for those two 
targets. Beside that restrict debug entry value support to be emitted
for LimitedDebugInfo info and FullDebugInfo. Other types of debug info
do not have functions nor variables debug info.
