Fixes #88818. For the following example:

struct S { }
impl for S { }

the current output is:

error: missing trait in a trait impl
 --> t1.rs:2:5
  |
2 | impl for S { }
  |     ^

With my changes, I get:

error: missing trait in a trait impl
 --> t1.rs:2:5
  |
2 | impl for S { }
  |     ^
  |
help: add a trait here
  |
2 | impl Trait for S { }
  |      +++++
help: for an inherent impl, drop this `for`
  |
2 - impl for S { }
2 + impl S { }
  |
