[Bug middle-end/19984] New: nan should be C99 built-in

[jsm28 at gcc dot gnu dot org]

The functions nan, nanf, nanl should be C99 built-in functions rather
than just being built-in in the __builtin_ form.

They were wrongly C90 built-ins, changed to be __builtin_ only to fix
bug 14635.  At that time bug 14649 meant they shouldn't be C99 built-ins,
but bug 14649 has been fixed so they now can be C99 built-ins.
