nir: Allow internal changes to the instr in nir_shader_lower_instructions().

v3d's NIR txf_ms lowering wants to swizzle around the input coordinates in
NIR, but doesn't generate a new txf_ms instructions as replacement.  It's
pretty easy to allow that in nir_shader_lower_instructions, and it may be
common in lowering passes.
