8e83afa61f don't emit lifetime lints for code inside macros.

0a25944f78 Auto merge of #5294 - tmiasko:trait-ptr-cmp, r=Manishearth 
Lint unnamed address comparisons

Functions and vtables have an insignificant address. Attempts to compare such addresses will lead to very surprising behaviour. For example: addresses of different functions could compare equal; two trait object pointers representing the same object and the same type could be unequal.

Lint against unnamed address comparisons to avoid issues like those in rust-lang/rust#69757 and rust-lang/rust#54685.

changelog: New lints: [`fn_address_comparisons`] [#5294](https://github.com/rust-lang/rust-clippy/pull/5294), [`vtable_address_comparisons`] [#5294](https://github.com/rust-lang/rust-clippy/pull/5294)

`unused_self` false positive

fixes #5351

Remove the for loop in `unused_self` so that lint enabled for one method doesn't trigger on another method.

Move verbose_file_reads to restriction

cc #5368

Using `File::read` instead of  `fs::read_to_end` does make sense in multiple cases, so this lint is rather restriction, than complexity
