This fixes a silly regression introduced in 0.4.50 that broke the search
hotkey (https://github.com/rust-lang/rust/pull/141457).

Cygwin defaults to rooting Windows paths in /cygdrive/X, while MSYS2
configures them to be /X. Regardless of configuration, drives are
always accessible as /proc/cygdrive/X, so use that.

interpret: add allocation parameters to `AllocBytes`
Necessary for a better implementation of [rust-lang/miri#4343](https://github.com/rust-lang/miri/pull/4343). Also included here is the code from that PR, adapted to this new interface for the sake of example and so that CI can run on them; the Miri changes can be reverted and merged separately, though.

Properly analyze captures from unsafe binders
We need to represent the unsafe binder unwrap as an adjustment in HIR. Pretty straightforward b/c we already represent it as a projection elem in MIR.

interpret: do not force_allocate all return places
A while ago I cleaned up our `PlaceTy` a little, but as a side-effect of that, return places had to always be force-allocated. That turns out to cause quite a few extra allocations, and for a project we are doing where we marry Miri with a model checker, that means a lot of extra work -- local variables are just so much easier to reason about than allocations.
So, this PR brings back the ability to have the return place be just a local of the caller. To make this work cleanly I had to rework stack pop handling a bit, which also changes the output of Miri in some cases as the span for errors occurring during a particular phase of stack pop changed.
With these changes, a no-std binary with a function of functions that just take and return scalar types and that uses no pointers now does not move *any* local variables into memory. :)

fix: Properly implement `might_be_inside_macro_call()` using semantic information instead of syntactical hacks
|
|
Instead of a `Vec`, to avoid some allocations.
|
|
It never fails, so it doesn't need to return `Result`. And the
`ItemType` in the result is just a copy of the one passed in via the
`shortty` arg, so it can also be removed.

Most of the methods returning `impl Display` have `print` in their name.
This commit renames a few that didn't follow that convention.

[rustdoc] Unify type aliases rendering with other ADT
Fixes #140739.
Better reviewed one commit at a time.
Just one thing I'm wondering: should we also render non-`repr` attributes? If so, I wonder if we shouldn't simply change `clean::TypeAlias` to contain the other ADT directly (`Struct`, `Enum` and `Union`) and remove the `TypeAlias::generics` field.
Can be done in a follow-up too.

To avoids the early return and duplication of `Ok((url_parts, shortty,
fqp))`.
|
|
Currently it is passed an `fqp` slice which it calls `to_vec` on and
returns. This is a bit odd. It's better to let the call site clone if
necessary. (One call site does, one does not).
|
|
This reverts part of #91948, going back to returning a
`UrlPartsBuilder`. It makes the code simpler, and also avoids some
allocations.

instead of syntactical hacks
And rename it to `is_inside_macro_call()` accordingly.
|
|
It wasn't inside the source, because there was no source map.

bootstrap: clippy: set TESTNAME based on given paths
This addresses #104200 by setting the TESTNAME environment variable automatically based on the paths from run configs, marking a selected set of UI tests to be run.
Note that this does not filter out other unit tests using #[test].
