Merge #1862 
1862: Assoc item resolution refactoring (again) r=flodiebold a=flodiebold

This is #1849, with the associated type selection code removed for now. Handling cycles there will need some more thought.

2890a1450a remove confusing code 
I must confess I don't really understand what this code is trying to
do, but it definitely misreports changes during fixedpoint iteration,
and no tests fail if I remove it, so...

fe1dfd2b20 Refactor some more 
Type-relative paths (`<T>::foo`) also need to work in type context, for example
`<T>::Item` is legal. So rather than returning the type ref from the resolver
function, just check it before.

406280e52f Refactor associated item resolution more 
When resolving an associated item in value namespace, use the `Ty` lowering code
for the segments before the last instead of replicating it.

913ab1ec0a Resolve assoc types on type parameters 
E.g. `fn foo<T: Iterator>() -> T::Item`. It seems that rustc does this only for
type parameters and only based on their bounds, so we also only consider traits
from bounds.

Merge #1848 
1848: Parse `..` as a full pattern r=matklad a=ecstatic-morse

Resolves #1479.

This PR implements [RFC 2707](https://github.com/rust-lang/rfcs/pull/2707) in the parser. It introduces a new `DotDotPat` AST node modeled on `PlaceholderPat` and changes the parsing of tuple and slice patterns to conform to the RFC.

Notably, this PR does *not* change the resulting AST when `..` appears in a struct pattern (e.g. `Struct { a, b: c, .. }`). I *think* this is the behavior mandated by RFC 2707, but someone should confirm this.

1847: Allow an underscore as the identifier in `const` items r=matklad a=ecstatic-morse

[RFC 2526](https://github.com/rust-lang/rust/issues/54912) was recently stabilized, meaning `const _: i32 = 5;` is now a valid item.
