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.

; Check that the DAGCombiner does not crash with an assertion failure
; when performing a target specific combine to simplify a 'or' dag node
; according to the following rule:
; (or (and B, A), (and C, ~A)) => (VBSL A, B, C)
; The assertion failure was caused by an invalid comparison between APInt
; values with different 'BitWidth'.
