PNaCl ABI: Reduce the set of allowed "align" attributes on loads/stores
Change the ABI verifier to require "align 1" on non-atomic integer
accesses to prevent non-portable behaviour. Allow larger alignments
on floating point accesses as a concession to performance, because ARM
might not be able to do unaligned FP loads/stores efficiently.
Change StripAttributes to make pexes pass the ABI verifier.
Also update comments in StripAttributes to match some recent changes.
