It's indeed not hard to create builtin CPP macros for the
instances in libstdc++ right now.

That said, I do think it's important to be able to handle
__builtin_inf and __builtin_nan anywhere regular fp 
constants are valid, *and* that the final generated code
considers them constants, as opposed to runtime initialization.
