Auto merge of #135335 - oli-obk:push-zxwssomxxtnq, r=saethlin
codegen: store ScalarPair via memset when one side is undef and the other side can be memset Basically since `undef` can be any byte, it can also be the byte(s) that are in the non-undef parts of a value. So we can just treat the `undef` at not being there and only look at the initialized bytes and memset over them fixes #104290 based on https://github.com/rust-lang/rust/pull/135258
