[PATCH] D18624: [PGO] PGOFuncName meta data if PGOFuncName is different from function's raw name.

the reason for splitting the check is we don't need this check at all in
llvm instrument,-- as it's done per function. but I guess it does not
matter much to move it in to create -- it's only called once per function.
