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 use to make a difference back when the two were always the same, but in the presence of overloaded proname values we'd best try to use the C name instead.  AFAICT this change affects no existing code, but it is necessary to be able to get at some built-in functions that no macro was being generated for before.
