fa9a0aa77b ARM64: add acquire/release versions of the existing atomic intrinsics.
These will be needed to support IR-level lowering of atomic
operations.

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.
