ARM: mark various aliases with their architecture requirements.
If an alias inherits directly from InstAlias then it doesn't get any default
"Requires" values, so llvm-mc will allow it even on architectures that don't
support the underlying instruction.
This tidies up the obvious VFP and NEON cases I found.
