Rollup merge of #71314 - mibac138:cfg-version, r=petrochenkov
Implement RFC 2523, `#[cfg(version(..))]`

Hi! This is my first contribution to rust, I hope I didn't miss anything. I tried to implement this feature so that `#[cfg(version(1.44.0))]` works but the parser was printing an error that I wasn't sure how to fix so I just opted for implementing `#[cfg(version("1.44.0"))]` (note the quotes).

Tracking issue: #64796

Rollup merge of #71165 - lcnr:patch-2, r=Amanieu
`slice::fill`: use `T` instead of generic arg

implements https://github.com/rust-lang/rust/issues/70758#issuecomment-613994427

As the discussion in #70758 has shifted, I now use `T` instead of `&T`.

299bd12fe5 Point at associated types when they have a default type
Associated types with a default type in a trait can't be relied upon to
remain of that default type when in use, so literals of that type can't
be used in the trait's items. Point at the associated type and state
that information.

Reduce verbosity for associated consts of the wrong type.

3a795fba03 On type mismatch involving associated type, suggest constraint
When an associated type is found when a specific type was expected, if
possible provide a structured suggestion constraining the associated
type in a bound.

The extracted function can be used by the rest of bootstrap to detect if we've
already built an up-to-date LLVM (and so it's safe for us to either request it
