Rollup merge of #63464 - Mark-Simulacrum:deref-instance, r=eddyb 
Copy ty::Instance instead of passing by reference

ty::Instance is small and Copy, we should not be adding additional
indirection.

Fixes #63409.

Rollup merge of #63440 - RalfJung:ctfe-backtrace, r=oli-obk 
rename RUST_CTFE_BACKTRACE to RUSTC_CTFE_BACKTRACE

This matches `RUSTC_LOG`. Both affect only rustc, not any Rust program.

Rollup merge of #63346 - RalfJung:zeroed-lint, r=eddyb 
Lint on some incorrect uses of mem::zeroed / mem::uninitialized

Cc https://github.com/rust-lang/rust/issues/62825 and https://internals.rust-lang.org/t/make-mem-uninitialized-and-mem-zeroed-panic-for-some-types-where-0-is-a-niche/10605

This does not yet handle `NonNull`/`NonZero*`, but it is a start.

I also improved some doc issues I hit on the way, and added a useful helper to `TyS`.

EDIT: I added the relnotes label mostly as a proposal -- I think this is worth mentioning, but leave the decision up to the release team.

Rollup merge of #61969 - MikailBag:master, r=Centril 
Add #[repr(transparent)] for several types

In some functions, types mentioned in this PR are transmuted into their inner value.
Example for `PathBuf`: https://github.com/rust-lang/rust/blob/master/src/libstd/path.rs#L1132.
This PR adds `#[repr(transparent)]` to those types, so their correct behavior doesn't depend on compiler details. (As far as I understand, currently that line, converting `PathBuf` to `Vec<u8>`, is UB).

These impls prevent ergonomic use of the config (e.g., forcing us to use
RefCell) despite all usecases for these structs only using their Display

c57481001e Remove ReentrantMutex 
This drops the parking_lot dependency; the ReentrantMutex type appeared
to be unused (at least, no compilation failures occurred).

This is technically a possible change in behavior of its users, as
lock() would wait on other threads releasing their guards, but since we
didn't actually remove any threading or such in this code, it appears
that we never used that behavior (the behavior change is only noticeable
if the type previously was used in two threads, in a single thread
ReentrantMutex is useless).

8a068699a2 Auto merge of #63446 - Centril:refactor-lowering, r=oli-obk 
Refactor and categorize lowering wrt. items / exprs

Split lowering into more files along the lines of "expression related" and "item related".
Also refactor huge methods into smaller ones.

A next step might be to introduce "type related" and merge patterns and statements combined with expressions into "value related". There's still more work to do but the PR was getting too big :)
