Regression test for #82866
Saw that this issue was open when i was cleaning my old branch for #92237.
I am also not opposed to not adding an extra test and just closing #82866.
Fixes#82866
Stop flagging unexpected inner attributes as outer ones in certain diagnostics
Fixes#94340.
In the issue to-be-fixed I write that the general message _an inner attribute is not permitted in this context_ should be more specific noting that the “context” is the `include` macro. This, however, cannot be achieved without touching a lot of things and passing a flag to the `parse_expr` and `parse_item` calls in `expand_include`. This seems rather hacky to me. That's why I left it as it. `Span::from_expansion` does not apply either AFAIK.

Bump bootstrap compiler to 1.61.0 beta
This PR bumps the bootstrap compiler to the 1.61.0 beta. The first commit changes the stage0 compiler, the second commit applies the "mechanical" changes and the third and fourth commits apply changes explained in the relevant comments.

[bootstrap] Print the full relative path to failed tests
Before:
```
failures:
[ui] rustdoc-ui/intra-doc/feature-gate-intra-doc-pointers.rs
test result: FAILED. 0 passed; 1 failed; 0 ignored; 0 measured; 163 filtered out; finished in 0.45s
```
After:
```
failures:
[ui] src/test/rustdoc-ui/intra-doc/feature-gate-intra-doc-pointers.rs
test result: FAILED. 0 passed; 1 failed; 0 ignored; 0 measured; 163 filtered out; finished in 0.45s
```
This allows copy pasting the path or using Ctrl+Click in IDEs to go directly to the file, instead of having to edit the filename first.
Check that all hidden types are the same and then deduplicate them.
fixes#95538
This used to trigger a sanity check. Now we accept that there may be multiple places where a hidden type is constrained and we merge all of these at the end.
Ideally we'd merge eagerly, but that is a larger refactoring that I don't want to put into a backport
New mir-opt deref_separator
This adds a new mir-opt that split certain derefs into this form:
`let x = (*a.b).c;` to => `tmp = a.b; let x = (*tmp).c;`
Huge thanks to ``@oli-obk`` for his patient mentoring.
[bootstrap] Give a hard error when filtering tests for a file that does not exist
A common issue people run into when running compiletest is that filtering for files that don't exist is only a warning and not an error; running the whole test suite instead.
See for example https://rust-lang.zulipchat.com/#narrow/stream/182449-t-compiler.2Fhelp/topic/Question.20about.20compiletest.
This is especially bad when using `--bless`, which will modify all `.stderr` files.
Change bootstrap to require valid filters instead of discarding invalid filters and continuing.

enhance `ConstGoto` mir-opt by moving up `StorageDead` statements
From the `FIXME` in the implementation of `ConstGoto` miropt. We can move `StorageDead` statements up to the predecessor. This can expand the scope of application of this opt.

rustdoc: Fix item info display overflow
I came across this issue when reading local `Iterator` docs (reproduced in this screenshot):
The problem comes from the fact that `span` isn't `display: block` by default. Since `item-info` was already present on `<div>` in other places, I moved the last one to `div` as well.

Use revisions to track NLL test output (part 1)
The idea here is 2 fold: 1) When we eventually do make NLL default on, that PR should be systematic in "delete revisions and corresponding error annotations" 2) This allows us to look at test NLL outputs in chunks. (Though, I've opted here not to "mark" these tests. There are some tests with NLL revisions *now* that will be missed. I expect we do a second pass once we have all the tests with NLL revisions; these tests should be easy enough to eyeball.)
The actual review here should be "easy", but a bit tedious. I expect we should manually go through each test output and confirm it's okay.
The majority of these are either: 1) Only span change (the one I see most common is highlighting an entire function call, rather than just the function name in that call) 2) "E0308 mismatched types" -> "lifetime does not live long enough" 3) "E0495 cannot infer an appropriate lifetime for lifetime parameter" -> "lifetime does not live long enough" 4) "E0312 lifetime of reference outlives lifetime of borrowed content" -> "lifetime does not live long enough" 5) "E0759 `XXX` has an anonymous lifetime `'_` but it needs to satisfy a `'static` lifetime requirement" -> "lifetime does not live long enough" 6) "E0623 lifetime mismatch" -> "lifetime does not live long enough"
Other than the now lack of an error code, most of these look fine (with most giving more helpful suggestions now).
`rfc1623` output isn't great.

Let's r? ``@oli-obk`` since you've commented on the Zulip thread ;)
Let CTFE to handle partially uninitialized unions without marking the entire value as uninitialized.
follow up to #94411
To fix https://github.com/rust-lang/rust/issues/69488 and by extension fix https://github.com/rust-lang/rust/issues/94371, we should stop treating types like `MaybeUninit<usize>` as something that the `Scalar` type in the interpreter engine can represent. So we add a new field to `abi::Primitive` that records whether the primitive is nested in a union
