[PATCH] D45061: [NVPTX, CUDA] Use custom feature detection to handle NVPTX target builtins.

@echristo convinced me that this functionality can be implemented without growing a target-specific hook for custom interpretation of constraints used in TARGET_BUILTIN. Instead, we can hide unwieldy feature lists behind a macro.
