28a24ca471 [ARM64] Fix the information we give to the peephole optimizer for comparison.
ANDS does not use the same encoding scheme as other xxxS instructions (e.g.,
ADDS). Take that into account to avoid wrong peephole optimization.

81ea345894 [ARM64] Enable feature predicates for NEON / FP / CRYPTO.
AArch64 has feature predicates for NEON, FP and CRYPTO instructions.
This allows the compiler to generate code without using FP, NEON
or CRYPTO instructions.

58f58c97f0 [cleanup] Lift using directives, DEBUG_TYPE definitions, and even some
system headers above the includes of generated '.inc' files that
actually contain code. In a few targets this was already done pretty
consistently, but it wasn't done *really* consistently anywhere. It is
strictly cleaner IMO and necessary in a bunch of places where the
DEBUG_TYPE is referenced from the generated code. Consistency with the
necessary places trumps. Hopefully the build bots are OK with the
movement of intrin.h...

e90d4e2c69 AArch64/ARM64: enable directcond.ll test on ARM64.
Code change is because optimizeCompareInstr didn't know how to pull the
condition code out of FCSEL instructions.

7b837d8c75 ARM64: initial backend import
This adds a second implementation of the AArch64 architecture to LLVM,
accessible in parallel via the "arm64" triple. The plan over the
coming weeks & months is to merge the two into a single backend,
during which time thorough code review should naturally occur.

Everything will be easier with the target in-tree though, hence this
commit.
