When CodeExtractor moves instructions to a new function, debug
intrinsics referring to those instructions within the parent function
become invalid.

This results in the same verifier failure which motivated r344545, about
function-local metadata being used in the wrong function.

Change the type in a couple of lists and sets that only store physical
registers from unsigned to MCPhysRegs. The later is only 16bits and
saves us a bit of memory.

It was causing a crash because we were trying to get the definition
of a target register. Fixed the issue by adding a check and added

Summary:
Now that llvm demangler supports more generic customization, we can
implement type substitution directly on top of this API. This will allow
us to remove the specialized hooks which were added to the demangler to
support this use case.

CMake generates the exports file wrongly if the CMAKE_BUILD_TYPE is
unset for multi-configuration generators.

The generated file lib/cmake/polly/PollyExports-all.cmake then contains:

set_target_properties(LLVMPolly PROPERTIES
              IMPORTED_LOCATION_ my_build_dir/lib/LLVMPolly.so)
set_target_properties(Polly PROPERTIES
              IMPORTED_LOCATION_ my_build_dir/lib/libPolly.a)

The `sigrie` instruction signals a Reserved Instruction Exception.

Summary:
The NetBSD headers use internal indirect type for
standard *int*_t  definitions. The internal type is unrolled
inside the sanitizer into e.g. __int32_t from int32_t.

This symbol mangling causes pattern mismatch in
the interger truncation tests as they expect exact
types such as 'int32_t'.

Change the pattern rules so every acceptable internal
form of *int*_t will be accepted flawlessly.

Summary:
For platforms without preinit support (such as NetBSD/amd64) the
initialization routine __xray_init() was called in non-deterministic order
compared to other constructors. This caused breakage failures
as xray routines attempted to execute code with assumption of
being initialized, which was no always true.

Use GCC/Clang extension to set maximal priority to the constructor
calling __xray_init(). This code switches away from C++ lambda form,
as it did not allow to specify this compiler extension.

MSVCUndecoratedNameParser.cpp:25:36: warning: '&&' within '||' [-Wlogical-op-parentheses]

llvm-svn: 346220

Summary:
By now the context's SourceManager is now initialized everywhere that
ClangTidyCheck::registerMatcher() is called, so the call from run() seems
entirely redundant, and indeed all the tests pass.

This solves a problem with embedding clang-tidy: if using a DiagnosticsEngine
which already has file state, re-setting its SourceManager (to the same value)
causes an assertion.
(There are other ways to solve this problem, but this is the simplest).
