I don't really care whether we can evaluate it as a constant
expression or not outside of OpenCL mode; we just need to make sure it
doesn't evaluate to the wrong thing.

Actually, maybe we can make it work in OpenCL style for ExtVectors,
and gcc-style for other vectors?  I'd like to avoid having the
behavior here depend on whether we're in OpenCL mode.
