cdaee4aba7 pick off some easy cases for LUB/GLB in regions 
the goal here is to minimize creating variables

ad6ca084e7 don't create region vars in LUB coercions 
instead, extract the target region out of the autoderef loop

24bb607e7d Auto merge of #32282 - sfackler:panic-hook, r=alexcrichton 
Adjustments to the panic hook API

Rename `set_handler` and `take_handler` to `set_hook` and `take_hook` since we're not actually "handling" (i.e. fixing) anything.

Also alter `set_hook` to take a `Box<Fn(&PanicInfo) + 'static + Sync + Send>` rather than a parameterized closure since there's otherwise no easy way to re-register a hook that came from `take_hook`.

235d77457d Auto merge of #32080 - eddyb:transcendent, r=nikomatsakis 
Refactor call & function handling in trans, enable MIR bootstrap.

Non-Rust and Rust ABIs were combined into a common codepath, which means:
* The ugly `__rust_abi` "clown shoes" shim for C->Rust FFI is gone, fixes #10116.
* Methods, *including virtual ones* support non-Rust ABIs, closes #30235.
* Non-Rust ABIs also pass fat pointers in two arguments; the result should be identical.
* Zero-sized types are never passed as arguments; again, behavior shouldn't change.

Additionally, MIR support for calling intrinsics (through old trans) was implemented.
Alongside assorted fixes, it enabled MIR to launch 🚀 and do a *complete* bootstrap.
To try it yourself, `./configure --enable-orbit` *or* `make RUSTFLAGS="-Z orbit"`.

Expose the key of Entry variants for HashMap and BTreeMap.

This PR addresses [issue 1541](https://github.com/rust-lang/rfcs/issues/1541) by exposing the key of `HashMap` and `BTreeMap` entry variants. Basic tests are provided.
