Fix fn_to_numeric_cast UI tests 
This collapses both lint tests into one file.
Somehow allowing the other lint in the respective files did not work
correctly. Maybe that's fixed as part of fixing #3198.

Only run tests if pointer width is 64bit 
If the pointer width of the architechture is 32bit or something else,
then the tests will most likely produce different results.

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.

Make explicit_iter_loop and explicit_into_iter_loop allow-by-default, so
that people can turn them on if they want to enforce that style; avoid
presenting them as *the* idiomatic Rust style, rather than just *a* style.

350036a0c7 default_trait_access skips <F as Default>::default() 
This includes the type name, so is clear, and may be necessary.

There doesn't seem to be an obviously cleaner way to pull out the
literal text of the named type here.

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.

Add tests that index with a const value. 
In this commit tests were added to ensure that tests with a `const` index behaved as expected.
In order to minimize the changes to the test's corresponding `stderr`, the tests were appended to
the end of the file.

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

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

Generate let binding variable name for some cases 
Given a map call like `x.field.map ...` the suggestion will contain:
`if let Some(x_field) ...`

Given a map call like `x.map ...` the suggestion will contain:
`if let Some(_x) ...`

Otherwise it will suggest: `if let Some(_) ...`
