fbc93c0166 Lint against needless uses of collect() 
Handles cases of `.collect().len()`, `.collect().is_empty()`, and
`.collect().contains()`. This lint is intended to be generic enough to
be added to at a later time with other similar patterns that could be
optimized.

cc87dc7539 Move some range lints to complexity 
Recategorize `range_plus_one` and `range_minus_one` to `complexity`.
This moves `range_plus_one` out of the nursery as the inclusive range
syntax is now stable. Both are moved to `complexity` as it is more
consistent with other lints such as `int_plus_one`.

Remove incorrect note from string_add_assign docs 
The docs claim that `String::push_str` is better than `String::add` because `String::add` allocates a new string and drops the old one, but this is not true.  In fact, `add` reuses the existing string and grows it only if its capacity is exceeded, exactly like `push_str`.  Their performance is identical since `add` is just a wrapper for `push_str`:

```
    fn add(mut self, other: &str) -> String {
        self.push_str(other);
        self
    }
```

This is a follow-up to #2951 that extends the logic to allow for
returning references inside structs/enums/unions. This was a simple
oversight in the first version and it's surprisingly easy to handle.

Add known problem to needless_borrow lint 
The `needless_borrow` lint is temporarily disabled because of some false
positives it causes in combination with the `derive` macro.

However the documentation does not explain these issues, but instead
lists `Known problems: None`. To make it clear why this lint is
currently not enabled, a description of the false positives caused by
this lint has been added to the `Known problems` section.

Ryan Cumming
58459abd0c Allow pass by reference if we return a reference 
Currently this code will trigger `trivally_copy_pass_by_ref`:

```
struct OuterStruct {
    field: [u8; 8],
}

fn return_inner(outer: &OuterStruct) -> &[u8] {
    &outer.field
}
```

If we change the `outer` to be pass-by-value it will not live long
enough for us to return the reference. The above example is trivial but
I've hit this in real code that either returns a reference to either the
argument or in to `self`.

This suppresses the `trivally_copy_pass_by_ref` lint if we return a
reference and it has the same lifetime as the argument. This will likely
miss complex cases with multiple lifetimes bounded by each other but it
should cover the majority of cases with little effort.

fedd3ef711 Allows neg_cmp_op_on_partial_ord for external macros (fixes #2856). 
The macro always negates the result of the given comparison in its
internal check which automatically triggered the lint. As its an
external macro there was no chance to do anything about it which lead
to a white listing of all external macros to prevent further issues.

Removing lint for constant usize array indexing 
This commit removes the logic in this PR that linted out-of-bounds constant `usize` indexing on arrays. That case is already handled by rustc's `const_err` lint. Beyond removing the linting logic, the test file and its associated stderr were updated to verify that const `usize` indexing operations on arrays are no longer handled by this `indexing_slicing` lint.

Revisiting indexing_slicing test cases 
This commit contains a few changes. In an attempt to clarify which test cases should and should not produce stderr it became clear that some cases were being handled incorrectly. In order to address these test cases, a minor re-factor was made to the linting logic itself.

The re-factor was driven by edge case handling including a need for additional match conditions for `ExprCall` (`&x[0..=4]`) and `ExprBinary` (`x[1 << 3]`). Rather than attempt to account for each potential `Expr*` the code was re-factored into simply "if ranged index" and an "otherwise" conditions.

Second pass at addressing changes requested 
The changes reflected in this commit (requested in PR #2790) are as follows:

- Extended `INDEXING_SLICING` documentation to include the array type so that it is clearer when indexing operations are allowed.
- Variable `ty` defined identically in multiple scopes was moved to an outer scope so it's only defined once.
- Added a missing return statement to ensure only one lint is triggered by a scenario.
- Prettified match statement with a `let` clause. (I learned something new!)
- Added `&x[5..].iter().map(|x| 2 * x).collect::<Vec<i32>>()` and `&x[2..].iter().map(|x| 2 * x).collect::<Vec<i32>>()` to the test cases. The first _should trigger the lint/stderr_ and the second _should not_.

This commit represents an attempt to address changes requested in the process of reviewing PR #2790. 
The changes reflected in this commit are as follows:

- Revised `IndexingSlicingPass` struct name to IndexingSlicing for consistency with the rest of the code base.
- Revised match arm condition to use `(..)` shorthand in favor of `(_, _, _)`.
- Restored a couple telling variable names.
- Calls to `cx.span_lint` were revised to use `utils::span_help_and_lint`.
- Took a stab at refactoring some generalizable calls to `utils::span_help_and_lint` to minimize duplicate code.
- Revised INDEXING_SLICING declaration to pedantic rather than restriction.
- Added `&x[0..].get(..3)` to the test cases.

Rename instances of array_indexing 
This commit renames instances of `array_indexing` to `indexing_slicing` and moves the `indexing_slicing` lint to the `clippy_pedantic` group. The justification for this commit's changes are detailed in the previous commit's message.

Extend indexing_slicing lint 
Hey there clippy team! I've made some assumptions in this PR and I'm not at all certain they'll look like the right approach to you. I'm looking forward to any feedback or revision requests you have, thanks!

    Prior to this commit the `indexing_slicing` lint was limited to indexing/slicing operations on arrays. This meant that the scope of a really useful lint didn't include vectors. In order to include vectors in the `indexing_slicing` lint a few steps were taken.

    The `array_indexing.rs` source file in `clippy_lints` was renamed to `indexing_slicing.rs` to more accurately reflect the lint's new scope. The `OUT_OF_BOUNDS_INDEXING` lint persists through these changes so if we can know that a constant index or slice on an array is in bounds no lint is triggered.

    The `array_indexing` tests in the `tests/ui` directory were also extended and moved to `indexing_slicing.rs` and `indexing_slicing.stderr`.

    The `indexing_slicing` lint was moved to the `clippy_pedantic` lint group.

    A specific "Consider using" string was added to each of the `indexing_slicing` lint reports.

    At least one of the test scenarios might look peculiar and I'll leave it up to y'all to decide if it's palatable. It's the result of indexing the array `x` after `let x = [1, 2, 3, 4];`

    ```
    error: slicing may panic. Consider using `.get(..n)`or `.get_mut(..n)`instead
      --> $DIR/indexing_slicing.rs:23:6
       |
    23 |     &x[0..][..3];
       |      ^^^^^^^^^^^
    ```

    The error string reports only on the second half's range-to, because the range-from is in bounds!

    Again, thanks for taking a look.

    Closes #2536

This checks for things like

mutated in an expression to utils/usage.rs.

allow condition to be a block: by calling visit_expr of the visitor directly on the condition instead of walk_expr on the whole expression, we bypass the match to ExprWhile that calls visit_expr on the condition and visit_block on the body. This allow to re-enable visit_block in the visitor, as it won't be called on the while body
allow condition to use static variables: maintain a list of static variables used, and if they are mutable

e7a6b3e613 Update len_zero to handle comparisions with one 
I have added test cases for comparisons with zero and one.
While implementing handling of one, incorrect handlings of zero
were also fixed.

Prevent crash when macro is in different file 
This was caused by a macro in a different file.
The `target.span` was be in the file of the macro definition and the
`item.span` in the file of the calling code.

3373fa97e2 Add third variant to {pub_,}enum_variant_names examples 
The default value for `enum-variant-name-threshold` is 3, so the old examples (which only have two enum variants) don't actually trigger the lint by default.

Handle non-trivial nil closures 
`reduce_nil_closure` mixed together a) 'is this a nil closure?' and b) 'can it
be reduced to a simple expression?'. Split the logic into two functions so we
can still generate a basic warning when the closure can't be simplified.
