docs/test: add docs and a UI test for `E0514` and `E0519`
No UI test on `E0514`, it would need to compile with a different `rustc` version.

Data race spans
Fixes https://github.com/rust-lang/miri/issues/2205
This adds output to data race errors very similar to the spans we emit for Stacked Borrows errors. For example, from our test suite:
```
help: The Atomic Load on thread `<unnamed>` is here
--> tests/fail/data_race/atomic_read_na_write_race1.rs:23:13
|
23 | ... (&*c.0).load(Ordering::SeqCst) //~ ERROR: Data race detected between Atomic Load on thread `<unnamed>` and Write o...
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
help: The Write on thread `<unnamed>` is here
--> tests/fail/data_race/atomic_read_na_write_race1.rs:19:13
|
19 | *(c.0 as *mut usize) = 32;
| ^^^^^^^^^^^^^^^^^^^^^^^^^```
```
Because of https://github.com/rust-lang/miri/pull/2647 this comes without a perf regression, according to our benchmarks.
Provide more context on FileCheck failures
FileCheck provides 5 lines of context by default. This is often insufficient to analyze failures that happen in CI. Increase the amount of context to 100 lines.
fix vec::IntoIter::drop on high-alignment ZST
This fixes a soundness bug: IntoIter would call `drop_in_place` on an insufficiently aligned pointer. So if a ZST with alignment greater 1 had drop glue, that would be called with an unaligned reference. Since https://github.com/rust-lang/rust/pull/103957, Miri checks alignment even if the type does not have drop glue, which is how this bug was found.

Take revision into account in non-incremental-mode `// incremental` tests
A UI test I added in #105983 confusingly [failed](https://github.com/rust-lang/rust/pull/106031#issuecomment-1362558067) in a merge because two different revisions raced with each other for the same incremental directory for a (non-incremental-mode, i.e. `src/test/ui`) UI test.
Let's take the revision name into account when generating an incremental directory so that other UI tests that combine `// incremental` and `// revisions` won't race and cause possible flakiness in CI.
