Move where doc comment meant as comment check

[estebank]

The new place makes more sense and covers more cases beyond individual statements.

error: expected one of `.`, `;`, `?`, `else`, or an operator, found doc comment `//!foo
  --> $DIR/doc-comment-in-stmt.rs:25:22

LL |     let y = x.max(1) //!foo
   |                      ^^^^^^ expected one of `.`, `;`, `?`, `else`, or an operator

help: add a space before `!` to write a regular comment
   |
LL |     let y = x.max(1) // !foo

Fix #65329.
