Always run intrinsics lowering pass
Move intrinsics lowering pass from the optimization phase (where it would not run if -Zmir-opt-level=0), to the drop lowering phase where it runs unconditionally. The implementation of those intrinsics in code generation and interpreter is unnecessary. Remove it.
