clippy::cargo_common_metadata: check for license-file
When license property is missing in Cargo.toml check for license-file
as it may be used instead of the former. The check implemented here is
very naive as it only verifies that the field is present and is not
empty. More scrutiny can be applied by verifying the file is actually
present.
Fixes#4517

#4542 remove machine applicable suggestion
This helps #4542 (but does not completely resolve) by removing the machine applicable suggestion (which was incorrect) for that case.
I would have preferred to fix the machine applicable suggestion to handle format strings, but that's a bit beyond my current understanding of the clippy codebase. I'd be happy to give it a try given some guidance.
changelog: only produce machine applicable suggestions on `explicit_write` lint
Changes cast-lossless to a pedantic lint
As discussed in #4528, this moves the cast-lossless lint from `all` to `pedantic`.
I couldn't tell from description alone if it should also be removed from the complexity category, so I left it as part of complexity for now. I didn't see any impact to the tests from this change, but I could be wrong (as this is my first PR).
fixes#4528
changelog: Moves cast-lossless from default to checking only as a `pedantic` lint.
tests: disable incremental compilation in dogfood to reduce target dir size
tests: execute dogfood tests with incremental compilation disabled reduces target/ dir size of when "cargo test"ing by around 2 gigs.

Fix rustc breaking change: convert to Place's new boxed slice projection
Addressed breaking changes from rust-lang PR https://github.com/rust-lang/rust/pull/63420/
I'm not entirely sure the semantics are preserved as I don't have much knowledge about MIR yet. So this code was largely reverse-engineered from the PR above. I wouldn't be surprised if I did something wrong :).
I followed the instructions to pull latest rustc from master and verified the build break I was seeing in my PR for cast-lossless in Travis CI. With these changes, it compiles again and all tests pass.

Fix incorrect swap suggestion
Clippy suggests using swap on fields belonging to the same owner causing two mutable borrows of the owner.
Disclosure: This is my first time working with clippy and rusts HIR. I'm very grateful for assistance and suggestions to improve the PR.
fixes#981
changelog: Fix false positive in `manual_swap` lint
