Rollup merge of #5248 - ThibsG:ConstValues, r=flip1995 
Add lint on large non scalar const

This PR adds the new lint `non_scalar_const` that aims to warn against `const` declaration of large arrays. For performance, because of inlining, large arrays should be preferably declared as `static`.

Note: i made this one to warn on all const arrays, whether they are in a body function or not. I don't know if this is really necessary, i could just reduce this lint to variables out of function scope.

Fixes: #400

changelog: add new lint for large non-scalar types declared as const

Refactor: Use rustc's `match_def_path`

This replaces our match_def_path implementation with the rustc one.

Note that we can't just use it in all call sites because of the
`&[&str]` / `&[Symbol]` difference in Clippy/rustc.

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.

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 ?
