b5e6d6db41 Auto merge of #5134 - flip1995:snippet_block, r=phansch 
Make it possible to correctly indent snippet_block snippets

This adds a `indent_relative_to` arg to the `{snippet,expr}_block` functions. This makes it possible to keep the correct indentation of block like suggestions.

In addition, this makes the `trim_multiline` function private and adds a `indent_of` function, to get the indentation of the first line of a span.

The suggestion of `needless_continue` cannot be made auto applicable, since it would be also necessary to remove code following the linted expression. (Well, maybe it is possible, but I don't know how to do it. Expanding the suggestion span to the last expression, that should be removed didn't work)

6b5419412e Auto merge of #5081 - Areredify:vec_box_threshold, r=flip1995 
add size parameter for `vec_box`  lint

changelog: add size threshold for the `vec_box` lint, currently 4096 bytes (one page) (subject to change). Closes #3547.

diff is a little bit confusing due to some refactoring (moving free functions to lint struct functions), relevant portion is [this](https://github.com/rust-lang/rust-clippy/compare/master...Areredify:vec_box_threshold?expand=1#diff-1096120ca9143af89dcc9175ea92b54aR294-R298). In hindsight should've been different commits, but oh well.

be09bb47db Auto merge of #5034 - ThibsG:MatchWildErrArmImprove5024, r=flip1995 
Match wild err arm improvements

This lint should trigger on other identifiers which have `_` prefix (such as `_e`) and only if they are unused in the panic block.

_Note_: the `is_unused` function is greatly inspired from `pat_is_wild` function in [loops lints](43ac9416d9/clippy_lints/src/loops.rs (L1689)).
I've been considering doing some refactoring, maybe in utils. Maybe this PR or a new one. What do you think ?

676f14baa0
Add custom ICE message that points to Clippy repo 
This utilizes https://github.com/rust-lang/rust/pull/60584 by setting
our own `panic_hook` and pointing to our own issue tracker instead of
the rustc issue tracker.

This also adds a new internal lint to test the ICE message.

**Potential downsides**

* This essentially copies rustc's `report_ice` function as
  `report_clippy_ice`. I think that's how it's meant to be implemented, but
  maybe @jonas-schievink could have a look as well =)

  The downside of more-or-less copying this function is that we have to
  maintain it as well now.
  The original function can be found [here][original].
* `driver` now depends directly on `rustc` and `rustc_errors`

Closes #2734

cc622608db new lints around #[must_use] fns 
`must_use_unit` lints unit-returning functions with a `#[must_use]`
attribute, suggesting to remove it.

`double_must_use` lints functions with a plain `#[must_use]`
attribute, but which return a type which is already `#[must_use]`,
so the attribute has no benefit.

`must_use_candidate` is a pedantic lint that lints functions and
methods that return some non-unit type that is not already
`#[must_use]` and suggests to add the annotation.

4d30b08027 Auto merge of #4569 - james9909:add-comparison-chain, r=oli-obk 
Add a new lint for comparison chains

changelog: Adds a new lint: `comparison_chain`.

`comparison_chain` lints all `if` conditional chains where all the conditions are binary comparisons on the same two operands and will suggest a rewrite with `match`.

Closes #4531.

f30bf69ec7 Auto merge of #4508 - rust-lang:reduced-symbolism, r=phansch 
Simplify `utils::match_def_path`, removing a FIXME

changelog: none

This removes the `Vec<Symbol>` allocation. We still need to call `cx.get_def_path`, but this should already have been interned, and I don't see how we can keep ergonomics of that function without allocating a `Vec`.
