The main thing I’m concerned about here is that I feel like there ought to be a better way of doing this than checking for and disallowing it in every place where we can have a subexpression in C.

CC @AaronBallman for opinions on this.

Also, if we’re doing it this way, then the check should definitely be factored out into a function in `Sema`.
