Auto merge of #106458 - albertlarsan68:move-tests, r=jyn514

Move src/test to the root

See MCP at rust-lang/compiler-team#573

There may be more changes needed.

The first commit is just the move of the files:
You can check that the first commit did not do anything else than renames by running
```
git diff --diff-filter=r -M100% <rust-lang remote>/master <first commit hash>
```
The output should be empty, because the filter excludes renames, and the match threshold for qualifying a rename is 100%.

The second one is mostly a "find and replace" of `src/test` to `tests` and whatever is needed to make CI pass.

What is left to do:
---

- [x] Move directory
- [ ] Change references to `src/test`
    - [x] Change references in-tree
    - [ ] Change references in submodules / out-of-tree docs
- [x] Make CI pass:
    - [x] Fix tidy
    - [x] Fix tests
    - [x] Bless tests if needed (shouldn't normally)
- [ ] Merge it !

-This test verifies a bug was fixed that otherwise generated this error:

-thread 'rustc' panicked at 'No counters provided the source_hash for function:
-    Instance {

-The `PartialOrd` derived by `Version` happened to generate a MIR that generated coverage
-without a code region associated with any `Counter`. Code regions were associated with at least
-one expression, which is allowed, but the `function_source_hash` was only passed to the codegen
-(coverage mapgen) phase from a `Counter`s code region. A new method was added to pass the
-`function_source_hash` without a code region, if necessary.
