8981860cad ARM64: Refactor away a few redundant helpers. 
The comment claimed that the register class information wasn't available
in the assembly parser, but that's not really true. It's just annoying to
get to. Replace the helper functions with references to the auto-generated
information.

91c655736e ARM64: Improve diagnostics for malformed reg+reg addressing mode. 
Make sure only general purpose registers are valid for offset regs and
that 32-bit regs are only valid for sxtw and uxtw extends.

thing. =]

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.
