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 !

-// #71602 reported a simple array comparison just generating a loop.
-// This was originally fixed by ensuring it generates a single bcmp,
-// but we now generate it as a load+icmp instead. `is_zero_slice` was
-// tweaked to still test the case of comparison against a slice,
-// and `is_zero_array` tests the new array-specific behaviour.
-// The optimization was then extended to short slice-to-array comparisons,
-// so the first test here now has a long slice to still get the bcmp.
