I think that's worth doing just on notational clarity grounds.
The small cycle savings doesn't excite me, but understanding
DirectFunctionCall1(textin, CStringGetDatum(foo)) just involves
more different bits of trivia than cstring_to_text(foo).

Yeah, with wide-impact patches like this you are always going to have
that problem. One point though is that we don't have to improve every
call site at the same time. I'd be inclined to put in the new functions
and hit some representative sample of utils/adt/ files in the first
commit, and then incrementally fix other stuff.
