Tweak fmgrtab generation so that the F_XXX macros that give OIDs for
built-in procedures are named after the prosrc field of pg_proc (ie,the actual C function name), not the proname field. This did not useto make a difference back when the two were always the same, but in thepresence of overloaded proname values we'd best try to use the C nameinstead. AFAICT this change affects no existing code, but it isnecessary to be able to get at some built-in functions that no macrowas being generated for before.
