Rollup merge of #124003 - WaffleLapkin:dellvmization, r=scottmcm,Ralf…

…Jung,antoyo

Dellvmize some intrinsics (use `u32` instead of `Self` in some integer intrinsics)

This implements rust-lang/compiler-team#693 minus what was implemented in #123226.

Note: I decided to _not_ change `shl`/... builder methods, as it just doesn't seem worth it.
