The `align_offset` method returns an `usize`, so using `add` makes more sense than using `offset`, which takes an `isize`.
They were resolved with modern hygiene, making this just a strange way to shadow lifetimes.
Declarations were already modernized, resulting in cases where a macro couldn't resolve it's own identifier.
Fixes rust-lang#52632 Existential types (soon to be 'impl trait' aliases) can either be delcared at a top-level crate/module scope, or within another item such as an fn. Previously, we were handling the second case incorrectly when recursively searching for defining usages - we would check children of the item, but not the item itself. This lead to us missing closures that consituted a defining use of the existential type, as their opaque type instantiations are stored in the TypeckTables of their parent function. This commit ensures that we explicitly visit the defining item itself, not just its children.

I'm relatively certain that SWIG was only needed for LLDB which is no longer built, and I'm hoping we can remove the xz install to remove the reliance on `brew` for our build (which is another point of failure for flaky networks).
In testing 4-core machines on Azure the `realpath_works_tricky` test in
the standard library is failing with "The directory name is invalid". In
attempting to debug this test I was able to reproduce the failure
locally on my machine, and after inspecing the test it I believe is
exploiting Unix-specific behavior that seems to only sometimes work on
Windows. Specifically the test basically executes:
mkdir -p a/b
mkdir -p a/d
touch a/f
ln -s a/b/c ../d/e
ln -s a/d/e ../f
and then asserts that `canonicalize("a/b/c")` and
`canonicalize("a/d/e")` are equivalent to `a/f`. On Windows however the
first symlink is a "directory symlink" and the second is a file symlink.
In both cases, though, they're pointing to files. This means that for
whatever reason locally and on the 4-core environment the call to
`canonicalize` is failing. On Azure today it seems to be passing, and
I'm not entirely sure why. I'm sort of presuming that there's some sort
of internals going on here where there's some global Windows setting
which makes symlinks behavior more unix-like and ignore the directory
hint.
In any case this should keep the test working and also fixes the test
locally for me.
Remove mentions of removed `offset_to` method from `align_offset` docs The `offset_to` method was deleted in rust-lang#52814. The replacement for the removed method is `wrapping_offset_from`. However, neither method takes an `usize` as argument, so I don't think that it makes sense to mention them.

std: Fix a failing `fs` test on Windows
In testing 4-core machines on Azure the `realpath_works_tricky` test in
the standard library is failing with "The directory name is invalid". In
attempting to debug this test I was able to reproduce the failure
locally on my machine, and after inspecing the test it I believe is
exploiting Unix-specific behavior that seems to only sometimes work on
Windows. Specifically the test basically executes:
mkdir -p a/b
mkdir -p a/d
touch a/f
ln -s a/b/c ../d/e
ln -s a/d/e ../f
and then asserts that `canonicalize("a/b/c")` and
`canonicalize("a/d/e")` are equivalent to `a/f`. On Windows however the
first symlink is a "directory symlink" and the second is a file symlink.
In both cases, though, they're pointing to files. This means that for
whatever reason locally and on the 4-core environment the call to
`canonicalize` is failing. On Azure today it seems to be passing, and
I'm not entirely sure why. I'm sort of presuming that there's some sort
of internals going on here where there's some global Windows setting
which makes symlinks behavior more unix-like and ignore the directory
hint.
In any case this should keep the test working and also fixes the test
locally for me. It's also worth pointing out that this test was made Windows compatible in rust-lang#31360, a pretty ancient PR at this point.
Add syntactic and semantic tests for rest patterns, i.e. `..` As per my first note in rust-lang#62254 (comment) this adds syntactic and semantic tests for `..` ("rest") patterns which were implemented in rust-lang#62550. r? @estebank
