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>

Closes: #3585
