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.

These functions are in the profile runtime. PGO comes later.
Unfortunately, there's only room for 16 characters in a Darwin section,
so use __llvm_prf_ instead of __llvm_profile_ for section names.

Remove the remaining explicit static initialization from translation
units, at least on Darwin. Instead, create a use of __llvm_pgo_runtime,
which will pull in required code from compiler-rt.
After this commit (and its pair in compiler-rt), a user can define their
own __llvm_pgo_runtime to satisfy this undefined symbol and call the
functions in compiler-rt directly.

line arguments and directories tree. The old toolchain selection heuristics
worked incorrectly when user has a reduced MIPS toolchain supports
the O32 ABI only.

There is no bound architecture for the dsymutil action in the driver. Trying
to check various properties of the target will cause an assertion failure
because the target doesn't get initialized without a bound architecture.

This patch improves the support for picking Multilibs from gcc installations.
It also provides a better approximation for the flags '-print-multi-directory'
and '-print-multi-lib'.
This reverts r201203 (i.e. re-applying r201202 with small fixes in
unittests/CMakeLists.txtto make the build bots happy).

Use the verify hook rather than the compile hook to represent the
-verify-pch action, and move the exising --verify-debug-info action
into its own subclass of VerifyJobAction. Incidentally change the name
printed by -ccc-print-phases for --verify-debug-info.

When building for i386 or x86_64 with IPHONEOS_DEPLOYMENT_TARGET set in the
environment, the toolchain correctly recognizes that the target platform is
the iOS simulator. The code in Darwin::addMinVersionArgs was not updated for
svn 197148, where isTargetIPhoneOS() was widely replaced by isTargetIOSBased().
This is kind of a strange case, though, because we probably ought to be
passing -ios_simulator_version_min to the linker, but according to the FIXME
in the code, we intentionally avoid that unless the -mios-simulator-version-min
option was used. I don't know whether it is safe to change that yet, so
for now, I am just fixing the assertion failure.

libc++) when the installation is within the system root.
This doesn't really help cross compiles much, but we don't (currently)
have a great story around libc++, cross compiles, and who is responsible
for building and/or installing the libraries. However, it handles the
very common case of non-cross builds in a way entirely consistent with
GCC, so I'm hopeful this won't really hose anyone.
This is the second patch that I think should be backported to 3.4 to
give folks an easy to checkout and install working Clang+libc++
toolchain.

Recent versions of the iOS simulator no longer require linking with the
crt1.o, dylib1.o, or bundle1.o files. The relevant code is now included in
libSystem for the simulator.

Now instead of just looking in the system root for it, we also look
relative to the clang binary's directory. This should "just work" in
almost all cases. I've added test cases accordingly.
This is probably *very* worthwhile to backport to the 3.4 branch so that
folks can check it out, build it, and use that as their host compiler
going forward.

Previously we had bodged together some hacks mapping MachO embedded
targets (i.e. mainly ARM v6M and v7M) to the "*-*-darwin-eabi" triple.
This is incorrect in both details (they don't run Darwin and they're
not EABI in any real sense).
This commit appropriates the existing "MachO" environment for the
purpose instead.

encodes the canonical rules for LLVM's style. I noticed this had drifted
quite a bit when cleaning up LLVM, so wanted to clean up Clang as well.
