Fix ICE with buffered lint referring to AST node deleted by everybody_loops
Fixes #87308 . Note the following comment:
https://github.com/rust-lang/rust/blob/08759c691e2e9799a3c6780ffdf910240ebd4a6b/compiler/rustc_lint/src/early.rs#L415-L417
As it turns out, this is not _always_ a bug, because `-Zunpretty=everybody_loops` causes a lot of AST nodes to be deleted, and thus some buffered lints will refer to non-existent node ids. To fix this, my changes simply ignore buffered lints if `-Zunpretty=everybody_loops` is enabled, which, from my understanding, shouldn't be a big issue because it only affects pretty-printing. Of course, a more elegant solution would only ignore buffered lints that actually point at deleted node ids, but I haven't figured out an easy way of achieving this.
For the concrete example in #87308 , the buffered lint is created [here](https://github.com/rust-lang/rust/blob/08759c691e2e9799a3c6780ffdf910240ebd4a6b/compiler/rustc_expand/src/mbe/macro_rules.rs#L145-L151 ) with the `lint_node_id` from [here](https://github.com/rust-lang/rust/blob/08759c691e2e9799a3c6780ffdf910240ebd4a6b/compiler/rustc_expand/src/mbe/macro_rules.rs#L319 ), i.e. it points at the macro _expansion_, which then gets deleted by `ReplaceBodyWithLoop` [here](https://github.com/rust-lang/rust/blob/08759c691e2e9799a3c6780ffdf910240ebd4a6b/compiler/rustc_interface/src/passes.rs#L377 ).

Consistently use 'supertrait'.
A subset of places referred to 'super-trait', so this changes them
to all use 'supertrait'. This matches 'supertype' and some other

Fix an ICE caused by type mismatch errors being ignored
This PR fixes #87771 . It turns out that the check on `compiler/rustc_typeck/src/check/demand.rs:148` leads to the ICE. I removed it because the early return in [`check_expr_assign`](https://github.com/theo-lw/rust/blob/dec7fc3ced5bc3c18d0e5d29921d087f93189cb8/compiler/rustc_typeck/src/check/expr.rs#L928 ) already prevents unnecessary error messages from the call to `check_expr_coercable_to_type`.

Add lint `equatable_if_let`
This is my attempt for #1716 . There is a major false positive, which is people may implement `PartialEq` in a different way. It is unactionable at the moment so I put it into `nursery`.
There is a trait `StructuralPartialEq` for solving this problem which is promising but it has several problems currently:
* Integers and tuples doesn't implement it.
* Some types wrongly implement it, like `Option<T>` when `T` doesn't implement it.
I consider them bugs and against the propose of `StructuralPartialEq`. When they become fixed, this lint can become a useful lint with a single line change.
