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.
This directory contains the source code of the rust project, including:

and its testslibstd

For more information on how various parts of the compiler work, see the rustc guide.
