This replaces the new_src parameter of nir_ssa_def_rewrite_uses_after()
with an SSA def, and rewrites all the users as needed.

We use the same nir_deref_mode_is_in_set helper that we use in
nir_lower_vars_to_explicit_types for the same reason. If there are any
generic pointers in play, we have to lower all generic pointer modes at
the same time or else we risk types getting out-of-sync.

LLVM loves take advantage of the fact that vec3s in OpenCL are 16B
aligned and so it can just read/write them as vec4s. This results in a
LOT of vec4->vec3 casts on loads and stores. One solution to this
problem is to get rid of all vec3 variables.
