nir: Un-inline nir_builder_alu_instr_finish_and_insert()

Browse Source 
This function is big and I don't think it will won't get meaningfully
constant-propagated during inlining without LTO.  Move it to a .c file so
we just have one copy, saving 2.8MB from libnir.a on an amd64 release
build.

No statistically significant performance difference on iris shader-db, n=8.
