Rollup merge of #130712 - compiler-errors:const-eval-error-reporting, r=BoxyUwU 
Don't call `ty::Const::normalize` in error reporting

We do this to ensure that trait refs with unevaluated consts have those consts simplified to their evaluated forms. Instead, use `try_normalize_erasing_regions`.

**NOTE:** This has the side-effect of erasing regions from all of our trait refs. If this is too much to review or you think it's too opinionated of a diagnostics change, then I could split out the effective change (i.e. erasing regions from this impl suggestion) into another PR and have someone else review it.

UI Tests

This folder contains rustc's UI tests.

Test Directives (Headers)

Typically, a UI test will have some test directives / headers which are special comments that tell compiletest how to build and intepret a test.

As part of an on-going effort to rewrite compiletest (see https://github.com/rust-lang/compiler-team/issues/536), a major change proposal to change legacy compiletest-style headers // <directive> to ui_test-style headers //@ <directive> was accepted (see https://github.com/rust-lang/compiler-team/issues/512.

An example directive is ignore-test. In legacy compiletest style, the header would be written as

// ignore-test

but in ui_test style, the header would be written as

//@ ignore-test

compiletest is changed to accept only //@ directives for UI tests (currently), and will reject and report an error if it encounters any comments // <content> that may be parsed as an legacy compiletest-style test header. To fix this, you should migrate to the ui_test-style header //@ <content>.
