35c948ff4a Fix lowering of FnOnce() without return type
This should result in an implicit `-> ()`, not leaving out the binding.

b26a472ccb Fix type mismatch caused by macros
MacroStmts should be completely transparent, but it prevented
coercion. (I should maybe give `infer_expr` and `infer_expr_inner`
better names.)

63614aafad Resolve any lifetime variables to 'static after inference
Chalk's unification can sometimes create lifetime variables, which we
currently don't really deal with, but at least we don't want to leak
them outside of inference.

Should fix #8919.

We can't do the easy hack that we did before anymore, where we kept
track of whether any inference variables changed since the last time we
rechecked obligations. Instead, we store the obligations in
canonicalized form; that way we can easily check the inference variables
to see whether they have changed since the goal was canonicalized.

Merge #8813
8813: Get some more array lengths! r=lf- a=lf-

This is built on #8799 and thus contains its changes. I'll rebase it onto master when that one gets merged. It adds support for r-a understanding the length of:

* `let a: [u8; 2] = ...`
* `let a = b"aaa"`
* `let a = [0u8; 4]`

I have added support for getting the values of byte strings, which was not previously there. I am least confident in the correctness of this part and it probably needs some more tests, as we currently have only one test that exercised that part (!).

Fixes #2922.

8799: Add basic support for array lengths in types r=flodiebold a=lf-

This recognizes `let a = [1u8, 2, 3]` as having type `[u8; 3]` instead
of the previous `[u8; _]`. Byte strings and `[0u8; 2]` kinds of range
array declarations are unsupported as before.

I don't know why a bunch of our rustc tests had single quotes inside
strings un-escaped by `UPDATE_EXPECT=1 cargo t`, but I don't think it's
bad? Maybe something in a nightly?

8539:  fix: Do not propose inherent traits in flyimports and import assists r=flodiebold a=SomeoneToIgnore

Closes https://github.com/rust-analyzer/rust-analyzer/issues/8520

I've went with a separate method approach, since the [highlighted code](https://github.com/rust-analyzer/rust-analyzer/issues/8520#issuecomment-819856337) has not`Type` and uses `Ty` to get his data, but the code I had to change has no access to `Ty` and has `Type` only.

I'd prefer getting rid of it, but it's used in the impl search and not
super easy to replace there (I think ideally the impl search would do
proper unification, but that's a bit more complicated).

92dcc53f94 Remove Ty::substs{_mut}
Almost all uses actually only care about ADT substs, so it's better to
be explicit. The methods were a bad abstraction anyway since they
already didn't include the inner types of e.g. `TyKind::Ref` anymore.

8371: Don't use HirDisplayWrapper when displaying SourceCode r=matklad a=Veykril

The issue was basically that when displaying for `DisplayTarget::SourceCode` some `hir_fmt` functions would create `HirDisplayWrapper`s which would then `fmt` these triggering the Display panic since `fmt::Display` can't fail the same way as `HirDisplay`. Simple fix is to just use `hir_fmt` directly. Should probably write that down somewhere in source, looking for a good spot to put that right now.

Fixes #8077, Fixes #8370

8364: Memory usage improvements r=jonas-schievink a=alexmaco

These are mostly focused on splitting up enum variants with large size differences between variants by `Box`-ing things up.

In my testing this reduces the memory usage somewhere in the low percentages, even though the measurements are quite noisy.

Alexandru Macovei
fb1f544e24 Use Box'es to reduce size of hir_def::expr::Expr from 128 to 72 bytes (on 64bit systems)
Rationale: only a minority of variants used almost half the size.
By keeping large members (especially in Option) behind a box
the memory cost is only payed when the large variants are needed.

This reduces the size Vec<Expr> needs to allocate.
