6985: Use /etc/os-release to check for NixOS r=matklad a=lnicola
Closes#5641
The motivation in #5641 isn't too strong, but /etc/os-release exists on pretty much every Linux distro, while /etc/nixos sounds like an implementation detail.

6982: Remove parentheses when inverting `!(cond)` r=matklad a=Jesse-Bakker
Followup to #6894
When inverting a composite condition twice, the parentheses were left. This also removes those unnecessary parentheses when applying the invert-if assist.

6978: Filter out empty rustc spans r=lnicola a=jonas-schievink
Hopefully, this fixes https://github.com/rust-analyzer/rust-analyzer/issues/6892 (I couldn't test it since r-a currently requires a too recent version of VS Code)

6921: Higher-ranked trait bounds for where clauses r=flodiebold a=Veykril
There is a slight problem with this which is also noted in a FIXME now but `LifetimeParameters` of these ForLifetime where clauses allocate the lifetimes in the corresponding arena as if they were lifetimes of the item itself and not just the clause they belong to. I wasn't entirely sure what I could do about this but given nothing really uses lifetimes like that currently I figured it might be fine? Open to suggestions for that problem.
