math.h: Define FP_FAST_FMA, FP_FAST_FMAF, FP_FAST_FMAL.

These are not strictly necessary to define, really, so we haven't
exactly been nonconformant.  But they tell programs when they can
enable fast paths by using the fma(3) family of functions.

math.h: Add math_errhandling, MATH_ERRNO, MATH_ERREXCEPT.
XXX Should maybe put a __math_errhandling in machine/math.h, but only
VAX uses MATH_ERRNO and that's not likely to change any time soon, so
this will serve for now with less churn.

math.h: Add missing file for math_errhandling test.

Add __TEST_FENV define to fix vax build

libm/t_errhandling.c: Put __TEST_FENV before any #includes.

This pattern avoids any potential problem with transitive inclusions
of fenv.h.  (No change here because nothing else this file includes
transitively pulls in fenv.h, but being in the habit of doing it this
way avoids a class of problems.)
