algorithm. Sink the 'A' + Attribute hash into each form so we don't
have to check valid forms before deciding whether or not we're going
to hash which will let the default be to return without doing anything.

This ensures DWARF consumers don't confuse these references for
definitions. I'd argue it might be nice to improve debuggers so we don't
need this, but it's just one field in an abbreviation anyway - so it
doesn't seem worth the fight.

The two identical implementations of __cpuid for X86 / X86_64 were
leftovers from my first iteration on the patch that implemented it.

Some build environments are missing the required headers.
This reverts r200544, r200547, r200551. This does not revert the change that
introduced READWRITE ioctl type.

MSVC always places the 'this' parameter for a method first. The
implicit 'sret' pointer for methods always comes second. We already
implement this for __thiscall by putting sret parameters on the stack,
but __cdecl methods require putting both parameters on the stack in
opposite order.
Using a special calling convention allows frontends to keep the sret
parameter first, which avoids breaking lots of assumptions in LLVM and
Clang.
Fixes PR15768 with the corresponding change in Clang.

Adding the ARM RT sources to the CMake files, and enabling some
sanitizers to also build on ARM. This is far from supported or
production quality, but enabling it to build will get us errors
that we can actually fix.
Having said that, the Compiler-RT and the Asan libraries are
know to work on some variations of ARM.

This change is a part of refactoring intended to have common signal handling behavior in all tools.
This particular CL moves InstallSignalHandlers() into sanitizer_common (making it InstallDeadlySignalHandlers()), but doesn't enable default signal handlers for any tool other than ASan.

Also rename internal_sigaction() into internal_sigaction_norestorer(), as this function doesn't fully
implement the sigaction() functionality on Linux.

loop vectorizer to not do so when runtime pointer checks are needed and
share code with the new (not yet enabled) load/store saturation runtime
unrolling. Also ensure that we only consider the runtime checks when the
loop hasn't already been vectorized. If it has, the runtime check cost
has already been paid.
I've fleshed out a test case to cover the scalar unrolling as well as
the vector unrolling and comment clearly why we are or aren't following
the pattern.

This should be the last routine patch: AArch64 does still delegate to
EmitARMBuiltinExpr, but the remaining instances have complications of
one sort or another so some more cunning thought will be needed.
