4b478a5731 Add a new lint ptr_as_ptr,
which checks for `as` casts between raw pointers
without changing its mutability
and suggest replacing it with `pointer::cast`.

976850b69b Auto merge of #6538 - Jarcho:vec_init_then_push, r=llogiq
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

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.

895191628d Auto merge of #6525 - phansch:fix-bless-in-subdirs, r=flip1995
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.

60919e416d Auto merge of #6526 - matthiaskrgr:version, r=Manishearth
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.

Website issue tracker link and better search performance

This PR implements some improvements to the website:
1. Added a "Search on Github" link to the "Known problems" section (Closes #5386)
    ![example_3](https://user-images.githubusercontent.com/17087237/102718215-e9f12500-42de-11eb-8c1b-487f8184aaf7.png)
    <details>
    <summary>Another mock up I created with the GitHub logo</summary>

    ![example_2](https://user-images.githubusercontent.com/17087237/102718281-3472a180-42df-11eb-99b8-7f6d76da2b55.png)

    </details>

2. Only starting the search after three letters and improving the search performance in general. (Followup #6477)

### Testing
These changes can be tested locally by:
1. Clone this branch
2. Download the current lint index from the [gh-pages branch](https://github.com/rust-lang/rust-clippy/blob/gh-pages/master/lints.json)
3. Put it next to the `util/gh-pages/index.html` and open the html file. Make sure that it can load the lint data. (Browsers can be a bit iffy when opening a local html page and loading data)

### Sources for search performance:
1. [A stackoverflow about angular filter performance](https://stackoverflow.com/questions/26876514/optimize-angular-filter-performance)
    * I selected a search debounce of 50ms that's fast enough to catch fast deletion and typing but responsive enough to not bother the user
2. [A stackoverflow about string comparison speeds](https://stackoverflow.com/questions/5296268/fastest-way-to-check-a-string-contain-another-substring-in-javascript)
3. [JS benchmarks for string search performance (`indexOf` seams to be the best)](https://jsben.ch/9cwLJ)

Note: The performance is still a bit poor when going from a specific lint to no search filter. I suspect that angular is recreating all lint items when the filter is cleared causing a major lag spike. The filter functions is at least optimized for little to no search.
