Tim Northover ca0f4dc4f0 AArch64/ARM64: move ARM64 into AArch64's place
This commit starts with a "git mv ARM64 AArch64" and continues out
from there, renaming the C++ classes, intrinsics, and other
target-local objects for consistency.

"ARM64" test directories are also moved, and tests that began their
life in ARM64 use an arm64 triple, those from AArch64 use an aarch64
triple. Both should be equivalent though.

This finishes the AArch64 merge, and everyone should feel free to
continue committing as normal now.

; Most important point here is that the promotion of the i1 works
; correctly. Previously LLVM thought that i64 was the appropriate SetCC output,
; which meant it proceded in two steps and produced an i64 -> i64 any_ext which
; couldn't be selected and faulted.
; It was expecting the smallest legal promotion of i1 to be the preferred SetCC
; type, so we'll satisfy it (this actually arguably gives better code anyway,
; with flag-manipulation operations allowed to use W-registers).
