mathbuiltins.def: Do not defined huge_val built-in.

	* mathbuiltins.def: Do not defined huge_val built-in.
	* trans-const.c (gfc_build_inf_or_huge): New function.
	* trans-const.h (gfc_build_inf_or_huge): New prototype.
	* f95-lang.c (gfc_init_builtin_functions): Don't defined
	huge_val built-ins.
	* trans-intrinsic.c (gfc_build_intrinsic_lib_fndecls): We don't
	have functions of type (*) (void) anymore.
	(gfc_conv_intrinsic_minmaxloc): Call gfc_build_inf_or_huge.
	(gfc_conv_intrinsic_nearest): Call gfc_build_inf_or_huge instead
	of generating a call to huge_val().
