ttn: Fix number of components for IF/UIF
NIR if statements only take one component, but TGSI registers are vec4. We're supposed to compare the x component, per https://docs.mesa3d.org/gallium/tgsi.html#opcode-IF. Fixes: f103bded ("ttn: Use nir control flow insertion helpers") Reviewed-by: Jason Ekstrand <jason@jlekstrand.net> Tested-by: Leo Liu <leo.liu@amd.com> Closes: #3585 Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/6956>
