[libstdc++] numeric_limits: fp is_modulo

[Richard Henderson]

The is_modulo predicate is only defined by LIA-1 for 
integer types.  Thus there is no conceivable reason
for the target to override.

Ok?

	* include/std/std_limits.h (__glibcpp_float_is_modulo,
	__glibcpp_double_is_modulo, __glibcpp_long_double_is_modulo): Kill.
	(numeric_limits<T>::is_modulo, T floating): Use false.
