Modified Files:
        src/tests/lib/libm: t_modf.c

Log Message:
tests/lib/libm/t_modf.c: Expand modf/modff/modfl tests.

1. Exercise more edge cases around the largest exponent that can
   represent non-integers.

2. - Verify modf can handle all cases modff can.
   - Veriy modf can handle some cases modff can't.
   - Verify modfl can handle all cases modf or modff can.
   - If long double isn't just double, verify modfl can handle some
     cases modf and modff can't.

3. Check infinities and NaN.

4. Verify oddness, i.e., modf(-x) = -modf(x).

5. Display more useful diagnostics in case any of this goes wrong.
