Ignore non-const ctor expressions in or_fn_call
Fixes https://github.com/rust-lang/rust-clippy/issues/1338
Should have been fixed by #919, however that focuses on const ctor expressions only, and `.or(Some(local))` isn't const.
This also automatically ignores things like `.or(Some(local.clone())` which we don't actually want to do; I need to figure out what to do here.

Allow allowing of toplevel_ref_arg lint
I'm not sure why some lints need the `HirId` to be able to recognize the
lint level attributes, but this commit makes the lint level attributes
work for `toplevel_ref_arg`.

Add run-rustfix for match_as_ref lint
* Extracts `match_as_ref` into separate file
* Adds `// run-rustfix` to `tests/ui/match_as_ref.rs`

Fix false positive in module_name_repetitions lint
This lint was triggering on modules inside expanded attrs, like
for example `#[cfg(test)]` and possibly more.
It was not reporting a location in #3892 because `span.lo()` and `span.hi()` both were 0.

Add Lint PathBufPushOverwrite
Closes#3923
This is a very simple Lint that checks if push is being called with a Root Path. Because that can make it overwrite the previous path.
I used std::path::Path to check if it's root, in order to keep it working across windows/linux environments instead of checking for '/'. Is that alright?
On the `if_chain!` block, Is there a way to make it short while getting the value of the first argument? I got the example from other lints.
Note that this is first Lint, I hope I got everything covered 🚀
Add run-rustfix for option_map_or_none lint
* Extracts `option_map_or_none` tests into separate file
* Adds `// run-rustfix` to `tests/ui/option_map_or_none.rs`

Add run-rustfix for deref_addrof lint
* renames `tests/ui/reference.{rs,stderr}` to
`tests/ui/deref_addrof.{rs,stderr}
* Moves small part of the testfile to a separate file as the lint
triggered again on the fixed code (as intended)
* Adds `// run-rustfix` to `tests/ui/deref_addrof.rs`

Fix ICE in decimal_literal_representation lint
Handling the integer parsing properly instead of just unwrapping.
Note that the test is not catching the ICE because plain UI tests
[currently hide ICEs][compiletest_issue]. Once that issue is fixed, this
test would fail properly again.

Fix `explicit_counter_loop` suggestion
#1670
This code seems to me to work, but I have two question.
* Because range expression desugared in hir, `Sugg::hir` doesn't add parenthesis to range expression. Which function is better to check range do you think, `check_for_loop_explicit_counter` or `hir_from_snippet`?
* Do you think we need to distinguish between range expression and struct expression that creates `std::ops::Range*`?
* Late Lint pass, catches:
* One liner: 0 -> null -> transmute
* One liner: std:null() -> transmute
* Const (which resolves to null) -> transmute
* UI Test case for Lint
* Updated test for issue 3849, because now the lint that code generated is in Clippy.
* Expanded `const.rs` miri-based Constant Folding code, to cover
raw pointers
The moved tests were part of `tests/ui/literals.rs` before. Now they are
placed in `tests/ui/unreadable_literal.rs`, which now also runs
`rustfix` on these 4 extra let statements.
Add `doc(include = ...)` detection to `missing_docs_in_private_items`
The whole `missing documentation in crate` part doesn't have any tests. If I should add test cases tell me.
Run rustfix for string_lit_as_bytes tests
This moves the `string_lit_as_bytes` tests into a new file and enables
rustfix tests for them.
cc #3603, #2038
Fix `boxed_local` suggestion
Don't warn about an argument that is moved into a closure.
ExprUseVisitor doesn't walk into nested bodies so use a new
visitor that collects the variables that are moved into closures.
Fixes#3739
