nir: Document a couple instances of parent_instr
nir_ssa_def::parent_instr and nir_src::parent_instr have the same name, but they mean really different things. I choose to save the next person the hour+ that I just spent figuring that out. Even now that I know, I doubt I'd notice in code review that someone typed foo->parent_instr when they actually meant foo->ssa->parent_instr. v2: Minor wording tweak in nir_ssa_def::parent_instr. Suggested by Jason. Signed-off-by: Ian Romanick <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]>
