Use LLVM-default spellings for amd64 on OpenBSD.

Browse Source 
OpenBSD spells the common 64-bit x86 architecture as amd64, while LLVM
defaults it to x86_64. A while back we tried to stick with the amd64
spelling, but this was difficult to make the change properly and
consistently. A while back we decided to just stick with LLVM spellings,
but there are a few minor cases missing.

This change is necessary for properly finding swiftrt.o.
