Szabolcs Nagy 1e5eb73545 math: add fma TODO comments about the underflow issue ...

The underflow exception is not raised correctly in some
cornercases (see previous fma commit), added comments
with examples for fmaf, fmal and non-x86 fma.

In fmaf store the result before returning so it has the
correct precision when FLT_EVAL_METHOD!=0
