Remove lazy_static completely and use once_cell feature instead
Follow-up to https://github.com/rust-lang/rust-clippy/pull/6120
This removes the last remaining `lazy_static` usages and replaces them with `SyncLazy` from the `once_cell` feature.

Fix two ICEs caused by ty.is_{sized,freeze}
Fixes#6153
Properly fixes#6139
The test case in #6153 is kind of weird. Even removing one of the arguments of the `foo` function prevented the ICE. I think this test case is actually minimal.

Expands `manual_memcpy` to lint ones with loop counters
Closes#1670
This PR expands `manual_memcpy` to lint ones with loop counters as described in https://github.com/rust-lang/rust-clippy/issues/1670#issuecomment-293280204
Although the current code is working, I have a couple of questions and concerns.
~~Firstly, I manually implemented `Clone` for `Sugg` because `AssocOp` lacks `Clone`. As `AssocOp` only holds an enum, which is `Copy`, as a value, it seems `AssocOp` can be `Clone`; but, I was not sure where to ask it. Should I make a PR to `rustc`?~~ The [PR]( https://github.com/rust-lang/rust/pull/73629) was made.
Secondly, manual copying with loop counters are likely to trigger `needless_range_loop` and `explicit_counter_loop` along with `manual_memcpy`; in fact, I explicitly allowed them in the tests. Is there any way to disable these two lints when a code triggers `manual_memcpy`?
And, another thing I'd like to note is that `Sugg` adds unnecessary parentheses when expressions with parentheses passed to its `hir` function, as seen here:
```
error: it looks like you're manually copying between slices
--> $DIR/manual_memcpy.rs:145:14
|
LL | for i in 3..(3 + src.len()) {
| ^^^^^^^^^^^^^^^^^^ help: try replacing the loop by: `dst[3..((3 + src.len()))].clone_from_slice(&src[..((3 + src.len()) - 3)])
```
However, using the `hir` function is needed to prevent the suggestion causing errors when users use bitwise operations; and also this have already existed, for example: `verbose_bit_mask`. Thus, I think this is fine.

Preserve raw strs for: format!(s) to s.to_string() lint
fixes#6142
clippy::useless_format will keep the source's string (after converting {{ and }} to { and }) when suggesting a change from format!() to .to_string() usage. Ie:
| let s = format!(r#""hello {{}}""#);
| ^^^^^^^^^^^^^^^^^^^^^ help: consider using `.to_string()`: `r#""hello {}""#.to_string()`
changelog: [`useless_format`]: preserve raw string literals when no arguments to `format!()` are provided.
New lint: Recommend using `ptr::eq` when possible
This is based almost entirely on the code available in the previous PR #4596. I merely updated the code to make it compile.
Fixes#3661.

Update release documentation
When updating the beta branch, we want to reset, instead of rebase. Otherwise we might produce again new commits on the beta branch, that aren't on the master branch.

Rename tables to typecheck_result()
While working on #6130, I noticed that part of the documentation was updated to use `LateContext::typeck_results`, but the paragraph still referred to the old `tables` field of `LateContext`.
