Rollup merge of #48834 - ysiraichi:suggest-remove-ref, r=estebank 
Suggest removing `&`s

This implements the error message discussed in #47744.
We check whether removing each `&` yields a type that satisfies the requested obligation.
Also, it was created a new `NodeId` field in `ObligationCause` in order to iterate through the `&`s. The way it's implemented now, it iterates through the obligation snippet and counts the number of `&`.

Rollup merge of #49077 - sinkuu:macro_use_typo, r=estebank 
Checks for unknown attributes before aborting due to unresolved macros

Fixes #49074

The ``attribute `...` is currently unknown to the compiler`` error was not shown if there are any unresolved macros, which might be caused by mistyped `macro_use`.

Rollup merge of #48706 - ehuss:main-not-found-in-crate, r=estebank 
Add crate name to "main function not found" error message.

Fixes #44798 and rust-lang/cargo#4948.

I was wondering if it might be cleaner to update the ui tests to add a simple `fn main() {}` for the unrelated tests.  Let me know if you would prefer that.

Disallow &a..=b and box a..=b in pattern. 
They are disallowed because they have different precedence than
expressions. I assume parenthesis in pattern will be soon stabilized and
thus write that as suggestion directly.

Stabilise feature(never_type). Introduce feature(exhaustive_patterns)

This stabilizes `!`, removing the feature gate as well as the old defaulting-to-`()` behavior. The pattern exhaustiveness checks which were covered by `feature(never_type)` have been moved behind a new `feature(exhaustive_patterns)` gate.
