The argument to `typedBufferStore` must be a vector of 4 elements, as we must
store 16 bytes exactly. The only exception to this is a vector of 2 doubles,
which isn't supported yet (I've filed #104423 for that).
That said, it'd probably be nice to get decent errors here if we get bad
textual IR or a frontend other than clang messes up, so I've added better
errors in the latest.
