adc7b8ea2d Fix completion with a partially unknown type
To test whether the receiver type matches for the impl, we unify the given self
type (in this case `HashSet<{unknown}>`) with the self type of the
impl (`HashSet<?0>`), but if the given self type contains Unknowns, they won't
be unified with the variables in those places. So we got a receiver type that
was different from the expected one, and concluded the impl doesn't match.

The fix is slightly hacky; if after the unification, our variables are still
there, we make them fall back to Unknown. This does make some sense though,
since we don't want to 'leak' the variables.

Fixes #3547.

9ce30281f6 Don't reuse the Chalk solver
This slows down analysis-stats a bit (~5% in my measurement), but improves
incremental checking a lot because we can reuse trait solve results.

d17c5416af Resolve Self::AssocTy in impls
To do this we need to carry around the original resolution a bit, because `Self`
gets resolved to the actual type immediately, but you're not allowed to write
the equivalent type in a projection. (I tried just comparing the projection base
type with the impl self type, but that seemed too dirty.) This is basically how
rustc does it as well.

Fixes #3249.

3494: Implement include macro r=matklad a=edwin0cheng

This PR implement builtin `include` macro.

* It does not support include as expression yet.
* It doesn't consider `env!("OUT_DIR")` yet.

3385: Fix #3373 r=matklad a=flodiebold

Basically, we need to allow variables in the caller self type to unify with the
impl's declared self type. That requires some more contortions in the variable
handling. I'm looking forward to (hopefully) handling this in a cleaner way when
we switch to Chalk's types and unification code.

e313efb992 Do array unsizing for method receivers
It turns out rustc actually only unsizes array method receivers, so we don't
need to do any trait solving for this (at least for now).

5fe220b987 Fix a common false-positive type mismatch
E.g. for `&{ some_string() }` in a context where a `&str` is expected, we
reported a mismatch inside the block. The problem is that we're passing an
expectation of `str` down, but the expectation is more of a hint in this case.
There's a long comment in rustc about this, which I just copied.

Also, fix reported location for type mismatches in macros.

f1f45f9191 Fix handling of const patterns
E.g. in `match x { None => ... }`, `None` is a path pattern (resolving to the
option variant), not a binding. To determine this, we need to try to resolve the
name during lowering. This isn't too hard since we already need to resolve names
for macro expansion anyway (though maybe a bit hacky).
