[llvm-commits] PATCH: Add 64-bit architecture predicate to llvm::Triple

This looks ok to me. One random thought - msp430 is 16 bit target. And
I have some plans to do something  in msp430 world again.
Does this make sense to query for "bitness" of the platform instead?
So, we can return e.g. whether the platform is 16 or 32 or 64 bits?
