* Fix a common false-positive type mismatchFlorian Diebold2020-02-291-4/+4
| | | | | | | | | 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.

* Handle impl Trait more correctlyFlorian Diebold2019-12-151-0/+1
| | | | | | | When calling a function, argument-position impl Trait is transparent; same for return-position impl Trait when inside the function. So in these cases, we need to represent that type not by `Ty::Opaque`, but by a type variable that can be unified with whatever flows into there.

* Don't unify within a referenceFlorian Diebold2019-12-061-11/+10
| | | | | | | If we are expecting a `&Foo` and get a `&something`, when checking the `something`, we are *expecting* a `Foo`, but we shouldn't try to unify whatever we get with that expectation, because it could actually be a `&Foo`, and `&&Foo` coerces to `&Foo`. So this fixes quite a few false type mismatches.
