This completes the port of r204814 (cpirker "AArch64_BE function argument passing for ARM ABI") from AArch64 to ARM64, and fixes a bunch of issues found during later development along the way. The biggest of these was that the alignment fixup logic wasn't replicated into all the places it should have been. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208192 91177308-0d34-0410-b5e6-96231b3b80d8
