math: fix comparision macros (isless etc) when FLT_EVAL_METHOD!=0

This is a change in ISO C11 annex F (F.10.11p1), comparision macros
can't round their arguments to their semantic type when the evaluation
format has wider range and precision. (ie. they must be consistent with
the builtin relational operators)
