This option disables the validation of binary UUIDs. This is useful
in environments where the `otool` binary is not available.

AMDGPU uses some custom code predicates for testing alignments.
I'm still having trouble comprehending the behavior of predicate bits
in the PatFrag hierarchy. Any attempt to abstract these properties
unexpectdly fails to apply them.

Add a new serializer, using a binary format based on the LLVM bitstream
format.
This format provides a way to serialize the remarks in two modes:
1) Separate mode: the metadata is separate from the remark entries.
2) Standalone mode: the metadata and the remark entries are in the same
file.
The format contains:
* a meta block: container version, container type, string table,
external file path, remark version
* a remark block: type, remark name, pass name, function name, debug
file, debug line, debug column, hotness, arguments (key, value, debug
file, debug line, debug column)
A string table is required for this format, which will be dumped in the
meta block to be consumed before parsing the remark blocks.
On clang itself, we noticed a size reduction of 13.4x compared to YAML,
and a compile-time reduction of between 1.7% and 3.5% on CTMark.

Summary:
This commit achieves the following:
- Functions used to return a `TypeSystem *` return an
`llvm::Expected<TypeSystem *>` now. This means that the result of a call
is always checked, forcing clients to move more carefully.
- `TypeSystemMap::GetTypeSystemForLanguage` will either return an Error or a
non-null pointer to a TypeSystem.

As of svn rL367298, SymbolFileDWARF locks the module in many cases where
it needs to parse some aspect of the DWARF symbol file.
SymbolFileDWARF::ParseLineTable needs to lock the module because
SymbolVendor::ParseLineTable no longer locks it.
llvm-svn: 367358
Summary:
LoopRotate may simplify instructions, leading to the new instructions not having memory accesses created for them.
Allow this behavior, by allowing the new access to be null when the template is null, and looking upwards for the proper defined access when dealing with simplified instructions.

UBSan-Standalone-x86_64 :: TestCases/TypeCheck/Function/function.cpp currently
FAILs on Solaris/x86_64:
clang-9: error: unsupported option '-fsanitize=function' for target 'x86_64-pc-solaris2.11'
AFAICS, there's nothing more to do then enable that sanitizer in the driver (for x86 only),
which is what this patch does, together with updating another testcase.
Tested on x86_64-pc-solaris2.11.

When looping over the difference architectures in a fat binary, we
modify the link options before dispatching the link step to a different
thread. Passing the options by cont reference is not thread safe, as we
might modify its fields before the whole sturct is copied over.
Given that the link options are already stored in the DwarfLinker, we
can easily fix this by passing a copy of the link options instead of a
reference, which would just get copied later on.

All other files are already C++ and the build system has always
passed '-x c++' for C files, effectively compiling them as C++.
To stay warning free we need one fix in ittnotify_static.{c,cpp}:
The variable dll_path can be written to, so it must not be const.
GCC complained with -Wcast-qual and I think it's right.

LoopInfo can be easily preserved by passing it to the functions that
modify the CFG (SplitCriticalEdge and MergeBlockIntoPredecessor.
SplitCriticalEdge also preserves LoopSimplify and LCSSA form when when passing in
LoopInfo. The test case shows that we preserve LoopSimplify and
LoopInfo. Adding addPreservedID(LCSSAID) did not preserve LCSSA for some
reason.
Also I am not sure if it is possible to preserve those in the new pass
manager, as they aren't analysis passes.
