351c29d859 Fix handling of the binders in dyn/impl Trait 
We need to be more careful now when substituting bound variables (previously, we
didn't have anything that used bound variables except Chalk, so it was not a
problem).

This is obviously quite ad-hoc; Chalk has more infrastructure for handling this
in a principled way, which we maybe should adopt.

e21b82e035 Upgrade Chalk 
Associated type values (in impls) are now a separate entity in Chalk, so we have
to intern separate IDs for them.

a1776b27c7 Use traits from where clauses for method resolution 
E.g. if we have `T: some::Trait`, we can call methods from that trait without it
needing to be in scope.

b8c1e402fa Make type walking infrastructure a bit nicer 
If/when we switch to using Chalk's Ty, we'll need to replace this by its `Fold`
trait, but I didn't want to import the whole thing just yet.

1834bae5b8 allow rustfmt to reorder imports 
This wasn't a right decision in the first place, the feature flag was
broken in the last rustfmt release, and syntax highlighting of imports
is more important anyway

a198d78bd1 cache chalk queries 
This gives a significant speedup, because chalk will call these
functions several times even withing a single revision. The only
significant one here is `impl_data`, but I figured it might be good to
cache others just for consistency.

The results I get are:

Before:

from scratch:   16.081457952s
no change:      15.846493ms
trivial change: 352.95592ms
comment change: 361.998408ms
const change:   457.629212ms

After:

from scratch:   14.910610278s
no change:      14.934647ms
trivial change: 85.633023ms
comment change: 96.433023ms
const change:   171.543296ms

Seems like a nice win!

b8cae2cf8f check for cancellation when executing queries 
Note that we can't just remove CheckCanceled trait altogether:
sometimes it's useful to check for cancellation while the query is
running! We do this, for example, in the name resolution fixed-point
loop.

f89d34be6a don't poison mutex around chalk 
We use panics for cancellation, so we could trigger panic while
holding the solver. std::sync::Mutex will be poisoned as a result,
which and all further attempts to use solver (from other threads) will
panic as well.

This commit switches to parking_lot::Mutex which just unlocks on panic.

c29a692137 Increase Chalk solver max_size back to 4 
Reducing it to 2 was just a failed attempt to see whether that would help fix
some slow cases; in fact, it can create new slow cases by replacing concrete
types by variables.
