Rollup merge of #110417 - jsoref:spelling-compiler, r=Nilstrieb

Spelling compiler

This is per https://github.com/rust-lang/rust/pull/110392#issuecomment-1510193656

I'm going to delay performing a squash because I really don't expect people to be perfectly happy w/ my changes, I really am a human and I really do make mistakes.

r? Nilstrieb

I'm going to be flying this evening, but I should be able to squash / respond to reviews w/in a day or two.

I tried to be careful about dropping changes to `tests`, afaict only two files had changes that were likely related to the changes for a given commit (this is where not having eagerly squashed should have given me an advantage), but, that said, picking things apart can be error prone.
