Add a stderr file length check to clippy_dev
This adds a check to `clippy_dev` that enforces a maximum line count for
`stderr` files. CI will fail if the line count is exceeded. It's
currently set to `320` lines.
Ideally this would be implemented in `compiletest-rs` but there are
plans to move Rust's `compiletest` into the `compiletest-rs` repository
and I don't want to do the work in `compiletest` twice. However, I also
don't want to wait until the move is done, so I added the check to
`clippy_dev` until it makes sense to add it to compiletest-rs.

Prevent symbocalypse
r? @Manishearth
This is strictly better, we can just not modify rustc and bump solely the clippy submodule and then implement diagnostic lang items without beta looming over us

Split redundant_closure lint
Move the method checking into a new lint called
`redundant_closures_for_method_calls` and put it in the pedantic group.
This aspect of the lint seems more controversial than the rest.

Properly hash enums
While I wrote this I was saved by a clippy lint... I accidentally fetched the discriminant of a reference to an enum and not of an enum.
changelog: reduce hash collisions during clippy-internal hashing
Make most macro checks also check for desugarings
We should audit the macro checks one by one and re-add `in_macro`. I suspect it's applicable to most of them.
