Rollup merge of #80040 - tmiasko:always-lower-intrinsics, r=Dylan-DPC
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.
