c++: Mark member functions as const [PR98951]

Browse Source 
These member functions look like they could be marked const, since
they don't modify any (non-mutable) class members.

	PR c++/98951
	* call.c (struct z_candidate): Mark rewritten and reversed as const.
	(struct NonPublicField): Mark operator() as const.
	(struct NonTrivialField): Likewise.
