A few (mostly CodeGen) parts of Clang were tightly coupled to the
AArch64 backend. Now that it's gone, they will not even compile.
I've also deduplicated RUN lines in many of the AArch64 tests. This
might improve "make check-all" time noticably: some of those NEON
tests were monsters.

Before -fstack-protector would always force a level of 1, even if the default
was 2.

Call it "libclang_rt.builtins-<arch>.a" to be consistent
with sanitizers/profile libraries naming. Modify Makefile
and CMake build systems and Clang driver accordingly.
Fixes PR19822.

Windows on ARM expects ARMv8 (restricted IT) conditional instructions only.
Force enable the restricted IT mode via the backend option when targeting WoA.

If `-shared` is specified, pull in a PIC-version of the profile runtime,
which was added to compiler-rt in r208947. I'm hoping this will get the
bots on my side.

None of our tests use /fallback, so this lets us gradually add RTTI
support without breaking projects using /fallback.

Don't bother with keeping the old support for x86_64 in 6.99.23+, just
use a single range. Update test cases for the always-on --eh-frame-hdr.

This patch is to get "-mno-unaligned-access" and "-munaligned-access"
work in front-end for ARM64 target.

After this patch clang will ignore -fdwarf2-cfi-asm and -ffno-dwarf2-cfi-asm and
always print assembly that uses cfi directives.
In llvm, MC itself supports cfi since the end of 2010 (support started
in r119972, is reported in the 2.9 release notes).
In binutils the support has been around for much longer. It looks like
support started to be added in May 2003. It is available in 2.15
(31-Aug-2011, 2.14 is from 12-Jun-2003).

Summary:
This patch adds a new flag -Rpass=. The flag indicates the name
of the optimization pass that should emit remarks stating when it
made a transformation to the code.
This implements the design I proposed in:
https://docs.google.com/document/d/1FYUatSjZZO-zmFBxjOiuOzAy9mhHA8hqdvklZv68WuQ/edit?usp=sharing
Other changes:
- Add DiagnosticIDs::isRemark(). Use it in printDiagnosticOptions to
print "-R" instead of "-W" in the diagnostic message.
- In BackendConsumer::OptimizationRemarkHandler, get a SourceLocation
object out of the file name, line and column number. Use that location
in the call to Diags.Report().
- When -Rpass is used without debug info a note is emitted alerting
the user that they need to use -gline-tables-only -gcolumn-info to
get this information.

MSVC doesn't have an option to enable TBAA, so make -fstrict-aliasing
and -fno-strict-aliasing available in clang-cl.

This introduces the definitions needed for the Windows on ARM target. Add
target definitions for both the MSVC environment and the MSVC + Itanium C++ ABI
environment. The Visual Studio definitions correspond to the definitions
provided by Visual Studio 2012.

This adds Clang support for the ARM64 backend. There are definitely
still some rough edges, so please bring up any issues you see with
this patch.
As with the LLVM commit though, we think it'll be more useful for
merging with AArch64 from within the tree.

-u behaviour is apparently not portable between linkers (see cfe-commits
discussions for r204379 and r205012). I've moved the logic to IRGen,
where it should have been in the first place.
I don't have a Linux system to test this on, so it's possible this logic
*still* doesn't pull in the instrumented profiling runtime on Linux.
I'm in the process of getting tests going on the compiler-rt side
(llvm-commits "[PATCH] InstrProf: Add initial compiler-rt test"). Once
we have tests for the full flow there, the runtime logic should get a
whole lot less brittle.

This follows the LLVM change to canonicalise the Windows target triple
spellings. Rather than treating each Windows environment as a single entity,
the environments are now modelled properly as an environment. This is a
mechanical change to convert the triple use to reflect that change.
