[PATCH] D37302: [Headers] Define *_HAS_SUBNORM for FLT, DBL, LDBL

It looks like all architectures that Clang supports have denorm support.  AFAICT, none of them have the "indeterminable" behavior.  So it seems safe to define these macros here.

@bruno The test lib/Headers/darwin.c will now pass even if the include_next for Darwin fails.  If there are more definitions in the Darwin float.h, I can update to test that definition instead of FLT_HAS_SUBNORM.
