Refactor `PrimitiveTypeTable` for Clippy
I removed `PrimitiveTypeTable` and added `PrimTy::ALL` and `PrimTy::from_name` in its place. This allows Clippy to use `PrimTy::from_name` for the `builtin_type_shadow` lint, and a `const` list of primitive types is deleted from Clippy code (the goal). All changes should be a little faster, if anything.
tests: ignore check_that_clippy_has_the_same_major_version_as_rustc()inside the rustc repo
Do not check if clippy version matches rustc version when runnning tests inside the rustc repo.
This makes sure that upstream rustc maintainers do not have to deal with our test failing/mismatching versions
when the rustc version bump is happening.

We already do the "don't run inside the rustc-repo" workaround for the dogfood test:
a507c27660/tests/dogfood.rs (L16)
changelog: None
This commit adds a new lint named `filter_map_identity`. This lint is
the same as `flat_map_identity` except that it checks for `filter_map`.

Use absolute path to Rust repo in ra_setup
This will convert the path to the Rust repo to an absolute path. This is
important for the clippy_lints/Cargo.toml file. Otherwise if a relative
path is passed, rst-analyzer won't find the Rust repo, because it starts
the relative path search from the clippy_lints dir, not the
rust-clippy dir where the ra_setup command was run from.

In other words, support:
`disallowed_methods = ["alloc::vec::Vec::new"]` (a free function) in
addition to
`disallowed_methods = ["alloc::vec::Vec::leak"]` (a method).
Improve the documentation to clarify that users must specify the full
qualified path for each disallowed function, which can be confusing for
reexports. Include an example `clippy.toml`.
Simplify the actual lint pass so we can reuse `utils::fn_def_id`.

changelog: Add new lint [`manual_flatten`] to check for loops over a single `if let` expression with `Result` or `Option`.
Fix file names of flat_map_identity test
This patch fixes the file names of the `flat_map_identity` test.
Previously, their names were started with `unnecessary_flat_map` even though the lint rule name is `flat_map_identity`. This inconsistency happened probably because the rule name was changed during the discussion in the PR where this rule was introduced.

Add .editorconfig
This adds a .editorconfig file to rust-lang/rust, matching Clippy's. It's not clear that this will benefit many people, but the cost is low and the rewards are potentially meaningful.
