11936: Ignore `Drop` and `Destruct` bounds for now r=flodiebold a=flodiebold
- `T: ~const Drop` has a special meaning in Rust 1.61 that we don't implement. (So ideally, we'd only ignore `~const Drop`, but this should be fine for now.)
- `Destruct` impls are built-in in 1.62 (current nightlies), so until the builtin impls are supported by Chalk, we ignore them as well. Since `Destruct` is implemented for everything in non-const contexts IIUC, this should also work fine.
Fixes#11932.

11920: Consider types of const generics r=flodiebold a=HKalbasi
fix#11913
We should emit type_mismatch in const generics, probably after #7434. Currently they will lead to a misleading, time of use type error (like the added test).

11930: internal: move function unsafety determination out of the ItemTree r=jonas-schievink a=jonas-schievink
Resolves some FIXMEs.
I've also renamed some FnFlags to be more explicit about what they represent (presence of keywords, not necessarily presence of semantics)

11925: internal: Add and use `HirFormatter::write_{str,char}` r=Veykril a=lnicola
Saves slightly over 3 KB of `text`, but comparing the total with that from two weeks ago in #11776, this is a losing battle (we're 951 KB larger).

11927: internal: Use bitflags for `FnFlags` r=jonas-schievink a=jonas-schievink
Previously we didn't do this because it didn't pull its weight, but now we actually do some bitops

11924: internal: remove `FnFlags::IS_IN_EXTERN_BLOCK` r=jonas-schievink a=jonas-schievink
This flag was determined purely based on the AST, which cannot work reliably since macros are allowed in `extern` blocks (in which case the function would not have an extern block parent in the AST).

11915: fix: Attempt to resolve paths in const arguments heuristically in IDE layer r=Veykril a=Veykril
While we don't support const args in type inference yet, we can at least
make use of the fallback path resolution to resolve paths in const args
in the IDE layer to enable some features for them.

11905: internal: Remove hir_expand macro recursion check r=jonas-schievink a=jonas-schievink
This check is insufficient to ensure finite macro nesting, and so all callers already have their own recursion limit, which makes this check redundant.
...at least I hope it's redundant. Would be great if someone could double-check this.
Originally, this check was added in https://github.com/rust-analyzer/rust-analyzer/pull/3671

11891: Better error message on Flycheck Error message (from: unactionable error message if we are using `clippy` as the checker) r=Veykril a=flipbit03
I have commented on this [S-unactionable issue](https://github.com/rust-analyzer/rust-analyzer/issues/6589) that the Flycheck error message should maybe provide a hint about what tool it actually runs. Searching on some places on the Internet I've found multiple people, including myself, losing copious amounts of time on the same issue. So I've decided to make this very small PR :-)
From an user experience standpoint, the current error message is unhelpful to the end user, because the end user does not know exactly what it needs to check/fix (outdated, broken, or missing `cargo clippy`). In my own case, `cargo clippy` was actually missing altogether (developing off `rust:1.59.0-bullseye` official Docker image).
Thanks in advance!

11904: internal: Wrap macros in expr position in `MacroExpr` node r=jonas-schievink a=jonas-schievink

11899: fix: Skip match check on patterns of unexpected TyKind::FnDef r=Veykril a=iDawer
Match checking does not expect patterns of `TyKind::FnDef` type.
It seems that in _rustc_ match checking is ruled out due to such type errors at the typecheck stage.
Spotted in #11319
