New lint: vec_init_then_push
fixes: #1483
This will trigger on `new`, `default`, and `with_capacity` when the given capacity is less than or equal to the number of push calls. Is there anything else this should trigger on?
changelog: Added lint: `vec_init_then_push`
collapsible_if: split collapsible_else_if into its own lint so we can enable/disable it particularly
This splits up clippy::collapsible_if into collapsible_if for
if x {
if y { }
}
=>
if x && y { }
and collapsible_else_if for
if x {
} else {
if y { }
}
=>
if x {
} else if y {
}
so that we can lint for only the latter but not the first if we desire.

Fix blessing of test output in subdirectories
The core issue was the usage of `reference_file_path.file_name()`, which
provided a non-existent path if the file to be updated was in a
subdirectory.
Instead we have to provide the whole path after 'tests/ui/' as the
'filename'. This part of the path is called `test_name` in the code now.

Initial support for Rust 2021.
Clippy treated Rust 2021 as Rust 2015, because 2018 was checked with `==` instead of `>=`. This fixes that, such that 2018-specific things are also enabled for 2021.

- Adds optional default values to const generic parameters in the AST
and HIR
- Parses these optional default values
- Adds a `const_generics_defaults` feature gate
make clippy version number correspond to rustc version number.
clippy 0.1.50 corresponds to rustc 1.50.x
This bumps the clippy version number from 0.0.212 to 0.1.50
Fixes#6499
Notes:
I used `cargo --version` because that way we can honour the version set in the `rust-toolchain` file.
When we bump the bootstrap compiler from 1.50 to 1.51, the version numbers will have to be changed to 1.51 or the test will fail.
