Rollup merge of #144983 - Oneirical:uncountable-integer, r=jieyouxu

Rehome 37 `tests/ui/issues/` tests to other subdirectories under `tests/ui/`

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.

r? ``@jieyouxu``
