Reorganisation of UI Tests

[rishi-techo-14]

Reorganize 11 tests in tests/ui/issues to appropriate subdirectories

This PR reorganizes tests in tests/ui/issues folder following the workflow suggested in the comment on #149411

Workflow:

• Move 11 tests to appropriate directories (such as pattern, typeck, traits, borrowck, closures).
• Rename each test in {reason}-issue-xxxx.rs format along with its corresponding .stderr file
• Add issue links and short description about what the test checks

All tests pass tidy locally using

python x.py test tidy

@rustbot r? @Kivooeo

[Kivooeo]

Remove the word "issue" from all test names and remove the issue numbers from those tests whose names are descriptive enough.

View changes since this review

[Kivooeo]

Also, remove the comments describing what the test is doing if the test is simple enough. However, keep an issue link and add a new line between your comment and the test.

Here's an example of what the test could look like: #152732.

[cyrgani]

This should not be moved to ui/traits, there are no traits involved at all.

I've finished the reorganization and cleanup. All 11 tests are successfully named and relocated, and tidy passes locally.
NOTE: My Windows PC is crashing(0xc0000005) during the full build when i try to run "python x.py test tests/ui --bless ", so I couldn't bless the .stderr files. I've pushed the changes so they can be blessed through CI.

I was referring to the @rustbot bless command.
I am unable to to run python x.py test tests/ui --bless on my local machine because the build consistently fails with a STATUS_ACCESS_VIOLATION (0xc0000005) while compiling library/core, which prevents me from running python x.py test tests/ui --bless myself.
So, since I can't generate the updated .stderr files locally due to the environment crash, I was hoping a maintainer could trigger @rustbot bless once the PR passes tidy, or kindly guide me if there is a way to trigger the CI-bless myself.

there is no CI-bless command or any way to do so... I think the best way you can do is run ./x test ui, then check what tests are failing and do ./x test path/to/test --bless by one on each failed test

Oh, I see. You can't run the compile test because you can't build the library. In that case, I could try pushing these changes directly into your branch.

I'm not sure how feasible this is for GSoC, but we could give you access to our cloud computing if you were chosen for the project.
