This is kinda obvious.

OK?

gcc/ChangeLog:

	* builtins.cc (fold_builtin_inf): Convert use of real_info to dconstinf.
	(fold_builtin_fpclassify): Same.
	* fold-const-call.cc (fold_const_call_cc): Same.
	* match.pd: Same.
	* omp-low.cc (omp_reduction_init_op): Same.
	* realmpfr.cc (real_from_mpfr): Same.
	* tree.cc (build_complex_inf): Same.
