I just tried these functions, and it seems like they are only
modifying the behavior of type promotions for a small subset of
operations (PromoteIntBinOp, PromoteIntShiftOp, PromoteExtend,
PromoteLoad, SimplifyBinOpWithSameOpcodeHands, visitSRL, visitTRUNCATE
that matter to the performance of i16 on X86.)
I don't like the "desirable" in the name of these functions: in the
case of Hexagon it is illegal to use an i8 predicate register for
anything else than setcc, brcon...
