CFI: Support self_cell-like recursion
Current `transform_ty` attempts to avoid cycles when normalizing `#[repr(transparent)]` types to their interior, but runs afoul of this pattern used in `self_cell`:
```
struct X<T> {
x: u8,
p: PhantomData<T>,
}
#[repr(transparent)]
struct Y(X<Y>);
```
When attempting to normalize Y, it will still cycle indefinitely. By using a types-visited list, this will instead get expanded exactly one layer deep to X<Y>, and then stop, not attempting to normalize `Y` any further.
This PR was split off from #121962 as part of fixing the larger vtable compatibility issues.

CFI: Strip auto traits off Virtual calls We already use `Instance` at declaration sites when available to glean additional information about possible abstractions of the type in use. This does the same when possible at callsites as well. The primary purpose of this change is to allow CFI to alter how it generates type information for indirect calls through `Virtual` instances. This is needed for the "separate machinery" version of my approach to the vtable issues (#122573), because we need to respond differently to a `Virtual` call to the same type as a non-virtual call, specifically [stripping auto traits off the receiver's `Self`](rust-lang/rust@54b15b0) because there isn't a separate vtable for `Foo` vs `Foo + Send`. This would also make a more general underlying mechanism that could be used by rcvalle's [proposed drop detection / encoding](rust-lang/rust@edcd1e2) if we end up using his approach, as we could condition out on the `def_id` in the CFI code rather than requiring the generating code to explicitly note whether it was calling drop.
Simplify an iterator search in borrowck diag Rather than `.into_iter().rev().find_position(...)`, this case can simply call `.iter().rposition(...)`.

…ays, r=oli-obk Encode implied predicates for traits In #112629, we decided to make associated type bounds in the "supertrait" AST position *implied* even though they're not supertraits themselves. This means that the `super_predicates` and `implied_predicates` queries now differ for regular traits. The assumption that they didn't differ was hard-coded in #107614, so in cross-crate positions this means that we forget the implied predicates from associated type bounds. This isn't unsound, just kind of annoying. This should be backported since associated type bounds are slated to stabilize for 1.78 -- either that, or associated type bounds can be reverted on beta and re-shipped in 1.79 with this patch. Fixes #122859

ci: Build gccjit from a git archive A full `git clone` of GCC includes quite a lot of history, and it's completely unnecessary for building it in CI. We can use a GitHub archive URL to get a simple tarball that is much faster to download. Also, the `gcc-build` directory can be removed after install to reduce the image size even further.
Replace `mir_built` query with a hook and use mir_const everywhere instead A small perf improvement due to less dep graph handling. Mostly just a cleanup to get rid of one of our many mir queries
Update upload-artifact to v4 This contains a breaking change around artifact merging no longer being done. This was not relied on, so it's fine.
