[Mesa-dev] [PATCH] Revert "nir: Turn imov/fmov of undef into undef."

[Timothy Arceri]

This reverts commit 6aa730000fea84a14b49828a4bb30761d43903bf.

This was changing the size of the undef to always be 1 (the number of inputs
to imov and fmov) which is wrong, we could be moving a vec4 for example.
