Existing decoration with `nnan`/`ninf` has inconvenient semantics. Having more powerfull and consistent solution can enable optimizations that are based on the knowledge of finitness of FP operands.

> This is to help simplify the GPU builtin math library distribution.

This patch is about parameter attribute only. How would it be used? Would it be a separate tool, that analyzes bitcode, or some follow-up patches are planned?
