Avoid generating indexed vector instructions for Exynos. This is needed for
fmla/fmls/fmul/fmulx. For example, the instruction
fmla v0.4s, v1.4s, v2.s[1]
is less efficient than the instructions
dup v2.4s, v2.s[1]
fmla v0.4s, v1.4s, v2.4s

We canonicalize V64 vectors to V128 through insert_subvector: the other
FMLA/FMLS/FMUL/FMULX patterns match that already, but this one doesn't,
so we'd fail to match fmls and generate fneg+fmla instead.
The vector equivalents are already tested and functional.

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.
