Fix unused_unit false positive
changelog: Fix `unused_unit` false positive
For some reason the `expr` of `stmt.node` didn't contain the expansion information, but the `stmt.span` does.
Fixes#4076
Account for trait alias when looking for defid
I hit the crash on the `expect` call when running clippy on rustc libcore.
Hopefully this will fix it.

Fix some suggestions for redundant_pattern_matching
.. and change the Applicability to `MaybeIncorrect`.
Fixes the problem displayed in https://github.com/rust-lang/rust-clippy/issues/4344#issuecomment-519206388.
We now append `{}` to the suggestion so that the conditional has the
correct syntax again.
(If we were to _remove_ the `if` instead, it would trigger the
`unused_must_use` warning for `#[must_use]` types.)

Add autofixable suggestion for unseparated integer literal suffixes
changelog: Add autofixable suggestion for unseparated integer literal suffixes
Somewhat WIP, since I haven't been able to get this working when adding `// run-rustfix` to `ui/literals.rs`. I think the issue is that there are multiple suggestions operating on one numerical literal, and I'm not sure what the best approach is to work around that.
Thanks
