I assume this is for vrecpe, right? I think it would be better
to post this as part of that patchset; it's easier to see the
rationale for adding the functions when you also have the
code that's using them.

Maybe we should just expose float32_default_nan in
softfloat.h somehow; that would match float32_zero,
float32_one, etc (ie it would not be a function).

No objection to this one.
