Merge rust-lang#9346

9346: Refactor / clean up hir_ty tests r=flodiebold a=flodiebold

Notable changes:
 - unify `check_types` and `check_mismatches` into `check`, which supports both kinds of annotations (`check_types` still exists because I didn't want to change all the annotations, but uses the same implementation)
 - because of that, `check_types` now fails on any type mismatches; also annotations always have to hit the exact range
 - there's also `check_no_mismatches` for when we explicitly just want to check that there are no type mismatches without giving any annotations (`check` will fail without annotations)
 - test annotations can now be overlapping (they point to the nearest line that has actual code in that range):
```
// ^^^^ annotation
//    ^^^^^^^^^ another annotation
```

9155: internal: replace attribute with equivalent whitespace r=jonas-schievink a=jonas-schievink

This is needed to that the `TokenMap` we create contains offsets that match the source. Currently the offsets don't match because the attribute is removed, shifting all subsequent token offsets by the attribute's text length.

Currently this fix has no visible effect because we don't remap tokens in attribute macros.
