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. :)

[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.

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].

Cleanup CodegenFnAttrFlags
- Rename `USED` to `USED_COMPILER` to better reflect its behavior.
- Reorder some items to group the used and allocator flags together
- Renumber them without gaps
rename internal panicking::try to catch_unwind
The public function is called `catch_unwind`, the intrinsic at some point got renamed to `catch_unwind` -- there's no reason to have the internal implementation of this still be called `try`, so let's rename it to match the rest.
