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.
3366: Simpilfy original_range logic r=matklad a=edwin0cheng
This PR fixed another [bug](https://github.com/rust-analyzer/rust-analyzer/issues/3000#issuecomment-592474844) which incorrectly map the wrong range of `punct` in macro_call and simplify the logic a little bit by introducing an `ascend_call_token` function.

3359: Remove AnalysisHost::type_of r=matklad a=edwin0cheng
This PR remove ` AnalysisHost::type_of` (It is subsume by hover now) and use `Semantics::type_of_x` to infer the type inside `hover` directly.
And this also solved a bug : Right now hovering on a string literal inside a macro will show up a `&str` popup correctly. (Except if that involved builtin macro, e.g. `println`)

3285: Handle trivia in Structural Search and Replace r=matklad a=adamrk
Addresses the second point of https://github.com/rust-analyzer/rust-analyzer/issues/3186.
Structural search and replace will now match code that has varies from the pattern in whitespace or comments.
One issue is that it's not clear where comments in the matched code should go in the replacement. With this change they're just tacked on at the end, which can cause some unexpected moving of comments (see the last test example).
