Rollup merge of #56661 - aelred:issue-55846, r=Mark-Simulacrum 
Add regression test for ICE

Fixes #55846 with a minimal (or as best as I can manage) test case. I tested this against 1.30.0 manually to confirm it crashes.

The issue seemed to have something to do with associated types. It's possible someone with more knowledge can shrink the test case down further, or make it clearer.

Rollup merge of #56620 - petrochenkov:noclutter, r=estebank 
resolve: Reduce some clutter in import ambiguity errors

Noticed in https://www.reddit.com/r/rust/comments/a3pyrw/announcing_rust_131_and_rust_2018/eb8alhi/.
The first error is distracting, but unnecessary, it's a *consequence* of the ambiguity error and appears because one of the ambiguous `actix` modules (unsurprisingly) doesn't have the expected name in it.

Fix ICE in region naming. 
This commit puts a fix in place for the ICE in region naming code so
that it doesn't break the compiler. However, this results in the
diagnostic being poorer as the borrow explanation that was causing the
ICE is not being added - this should be fixed as a follow-up.

Add suggestion for underscore binding fix. 
This commit emits a suggestion for adding an underscore binding to
arguments in trait methods that previously did not have a argument name
specified.

4bb5d35659 Auto merge of #56392 - petrochenkov:regensym, r=oli-obk 
Delay gensym creation for "underscore items" (`use foo as _`/`const _`) until name resolution

So they cannot be cloned by macros. See https://github.com/rust-lang/rust/pull/56303 for the discussion.

Mostly fix cross-crate use of underscore items by inverting the "gensyms are lost in metadata" bug as described in https://github.com/rust-lang/rust/pull/56303#issuecomment-442464695.
Fix unused import warnings for single-segment imports (first commit) and `use crate_name as _` imports (as specified in https://github.com/rust-lang/rust/pull/56303#issuecomment-442274118).
Prohibit accidentally implemented `static _: TYPE = EXPR;` (cc https://github.com/rust-lang/rust/pull/55983).
Add more tests for `use foo as _` imports.

This is dependent on the FCP for https://github.com/rust-lang/rfcs/pull/2591 being completed, but that should happen tomorrow, so there's little harm in opening this PR early.
