fb7edfa9a5 [ARM64] Switch the decoder, disassembler, instprinter and asmparser over to using AArch64-style system registers, and fix up test failures discovered in the process.

01229fa891 [ARM64] Move ARM64BaseInfo.{cpp,h} into a Utils/ subdirectory, a la AArch64. These files are required in the decoder, disassembler and parser, and a layering violation was imminent.

a493b7786a [ARM64] Shifted register ALU ops are reserved if sf=0 and imm6<5>=1, and also (for add/sub only) if shift=11.

6307036c7c [ARM64] MOVK with sf=0 and hw<1>=1 is unallocated. Shift amount for ADD/SUB instructions is unallocated if shift > 4.

7ac29214ce [ARM64] Register-offset loads and stores with the 'option' field equal to 00x or 10x are undefined.

3734a337e9 [ARM64] Fix 'assert("...")' to be 'assert(0 && "...")'. Otherwise, it is
no assert at all. ;] Some of these should probably be switched to
llvm_unreachable, but I didn't want to perturb the behavior in this
patch.

Found by -Wstring-conversion, which I'll try to turn on in CMake builds
at least as it is finding useful things.

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.
