What does this MR do and why?
agx: Re-index nir defs to reduce memory usage
nir_index_ssa_defs(..) will re-index the function impl and will update ssa_alloc. In almost all cases this will result in a lower ctx->alloc number which reduces memory usage in compiler passes that are using ctx-alloc to allocate memory.
