This commit:
- now makes `HirEqInterExpr::eq_block` take comments into account. Identical code with varying comments will no longer be considered equal.
- makes necessary adjustments to UI tests.
* Don't consider expansions of different macros to be the same, even if they expand to the same tokens
* Don't consider `cfg!` expansions to be equal if they check different configs.
In order to switch `clippy::uninlined_format_args` from pedantic to
style, all existing tests must not raise a warning. I did not want to
change the actual tests, so this is a relatively minor change that:
* add `#![allow(clippy::uninlined_format_args)]` where needed
* normalizes all allow/deny/warn attributes
* all allow attributes are grouped together
* sorted alphabetically
* the `clippy::*` attributes are listed separate from the other ones.
* deny and warn attributes are listed before the allowed ones
changelog: none
