Don't run `resolve_vars_if_possible` in `normalize_erasing_regions` Neither `@eddyb` nor I could figure out what this was for. I changed it to `assert_eq!(normalized_value, infcx.resolve_vars_if_possible(&normalized_value));` and it passed the UI test suite. <details><summary> Outdated, I figured out the issue - `needs_infer()` needs to come _after_ erasing the lifetimes </summary> Strangely, if I change it to `assert!(!normalized_value.needs_infer())` it panics almost immediately: ``` query stack during panic: #0 [normalize_generic_arg_after_erasing_regions] normalizing `<str::IsWhitespace as str::pattern::Pattern>::Searcher` #1 [needs_drop_raw] computing whether `str::iter::Split<str::IsWhitespace>` needs drop #2 [mir_built] building MIR for `str::<impl str>::split_whitespace` rust-lang#3 [unsafety_check_result] unsafety-checking `str::<impl str>::split_whitespace` rust-lang#4 [mir_const] processing MIR for `str::<impl str>::split_whitespace` rust-lang#5 [mir_promoted] processing `str::<impl str>::split_whitespace` rust-lang#6 [mir_borrowck] borrow-checking `str::<impl str>::split_whitespace` rust-lang#7 [analysis] running analysis passes on this crate end of query stack ``` I'm not entirely sure what's going on - maybe the two disagree? </details> For context, this came up while reviewing rust-lang#77467 (cc `@lcnr).` Possibly this needs a crater run? r? `@nikomatsakis` cc `@matthewjasper`
