Rollup merge of #144553 - Oneirical:uncountable-integer-4, r=jieyouxu

Rehome 32 `tests/ui/issues/` tests to other subdirectories under `tests/ui/`

rust-lang/rust#143902 divided into smaller, easier to review chunks.

Part of rust-lang/rust#133895

Methodology:

1. Refer to the previously written `tests/ui/SUMMARY.md`
2. Find an appropriate category for the test, using the original issue thread and the test contents.
3. Add the issue URL at the bottom (not at the top, as that would mess up stderr line numbers)
4. Rename the tests to make their purpose clearer

Inspired by the methodology that `@Kivooeo` was using.
