8938: internal: Fix#8931 r=flodiebold a=flodiebold
- and add some better checking for similar bugs
Co-authored-by: Florian Diebold <flodiebold@gmail.com>
The problem was the skipping of binders in
`resolve_method_call_as_callable`; this still doesn't use the _correct_
substitution, but at least it doesn't return a type with free variables
in it.
Fixes#8931.
8921: Resolve any lifetime variables to 'static after inference r=flodiebold a=flodiebold
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.

8901: fix: `fill_match_arms` hangs on a tuple of large enums r=matklad a=iDawer
+ Lazy computation of missing arms.
+ Convenience function to test lazy computation: `ide_assists::tests::check_assist_unresolved`.
Fixes#8835

8856: Use Chalk for unification r=flodiebold a=flodiebold
- use Chalk's unification, get rid of our own `unify`
- rewrite coercion to not use unification internals and to be more analogous to rustc
- fix various coercion bugs
- rewrite handling of obligations, since the old hacky optimization where we noted when an inference variable changes wasn't possible anymore
- stop trying to deeply resolve types all the time during inference, instead only do it shallowly where necessary
