[PATCH] AArch64: add support for llvm.aarch64.hint intrinsic

[Tim Northover]

I don't think the "mayLoad = ?" is any better. TableGen is still inferring "mayLoad = 1", we're just concealing that from the reader.

I think I'd go for the original code, with a comment that really these should be "mayLoad = 0" but that intrinsics' side effects aren't modelled with enough granularity for that to be possible.

Cheers.

Tim.
