librustc: Implement the syntax in the RFC for unboxed closure sugar. Part of issue #16640. I am leaving this issue open to handle parsing of higher-rank lifetimes in traits. This change breaks code that used unboxed closures: * Instead of `F:\|&: int\| -> int`, write `F:Fn(int) -> int`. * Instead of `F:\|&mut: int\| -> int`, write `F:FnMut(int) -> int`. * Instead of `F:\|: int\| -> int`, write `F:FnOnce(int) -> int`.

diagnostics: remove inconsistent English article "this" from E0107 Consider `tests/ui/const-generics/generic_const_exprs/issue-102768.stderr`, the error message where it gives additional notes about where the associated type is defined, and how the dead code lint doesn't have an article, like in `tests/ui/lint/dead-code/issue-85255.stderr`. They don't have articles, so it seems unnecessary to have one here. 2023-02-23 10:27:06 -07:00			`//~^ ERROR trait takes 0 generic arguments but 1 generic argument`
