This leaves us in the odd situation that this function accepts a vector of bools, but not a single bool. It seems we don't get here with a single bool because clang converts the bool to an integer first, but I don't see any reason that it shouldn't be allowed.

I find myself wondering if we should just be treating `cir.bool` as an integer type for type constraint purposes. @erichkeane What do you think?
