Basically copied and paste #59288/https://github.com/rust-lang/rust-clippy/pull/4080 with some modifications.

dfb41f4797 Separate out a hir::Impl struct 
This makes it possible to pass the `Impl` directly to functions, instead
of having to pass each of the many fields one at a time. It also
simplifies matches in many cases.

from type aliases, which is essentially the same as the ICE 4968.

Roadmap for 2021

[Rendered](https://github.com/flip1995/rust-clippy/blob/roadmap/doc/roadmap-2021.md)

This is the first time Clippy gets its own roadmap. The reason for this roadmap is, that with the Rust language growing, also Clippy is growing. With this keeping track of and implementing bigger projects gets quite hard. This roadmap should help in exactly this regard.

After having the approval of this roadmap by the Clippy team, we want to know from the community:

- What do you think in general about this roadmap?
- Are there any pain points in Clippy, that should be included here?
- What of the points listed here has the highest priority for you?

We're looking forward to getting your feedback!

changelog: Add roadmap for Clippy 2021

7f4599a848 Auto merge of #6557 - rail-rain:extending_cast_ptr_alignment, r=phansch 
Catch `pointer::cast` too in `cast_ptr_alignment`

Fixes #4708

Although there were some discussion in the issue, this PR implements the original feature. I think `cast_ptr_alignment` should exist as it is, separated from `ptr_as_ptr`.

`CLIPPY_TESTS` is understandably used in environments of Clippy users,
so we shouldn't use it in our test suite.

Fix FP for `boxed_local` lint in default trait fn impl

Fix FP on default trait function implementation on `boxed_local` lint.

Maybe I checked too much when looking if `self` is carrying `Self` in its bound type.
I can't find a good test case for this, so it could be too much conservative.
Let me know if you think only detecting `self` parameter is enough.

Fixes: #4804

Internal lint symbol comparisons

changelog: none

* Added awareness of `rustc_span::symbol::kw::*` symbols.
* Compare with const symbols: `symbol.as_str() == "self"` => `symbol == kw::SelfLower`
* Don't compare symbols by string: `a.as_str() == b.as_str()` => `a == b`
* Lint comparing with `to_ident_string` or `to_string` instead of `Symbol::as_str`.
