Hmm, the downside to the change being applied here is that 
`isPromotableIntegerType()` is a lie for HLSL and other callers are going to be 
surprised. I think a better way to achieve this same goal is to move 
`isPromotableIntegerType()` from `Type` to `ASTContext` so that it has access 
to the language options, and then hoist the language mode check so that 
`isPromotableIntegerType()` returns `false` for integer types in HLSL.
