1. Detect const in pattern with typo …

   When writing a constant name incorrectly in a pattern, the pattern will be identified as a new binding. We look for consts in the current crate, consts that where imported in the current crate and for local `let` bindings in case someone got them confused with `const`s.
   
   ```
   error: unreachable pattern
     --> $DIR/const-with-typo-in-pattern-binding.rs:30:9
      |
   LL |         GOOOD => {}
      |         ----- matches any value
   LL |
   LL |         _ => {}
      |         ^ no value can reach this
      |
   help: you might have meant to pattern match against the value of similarly named constant `GOOD` instead of introducing a new catch-all binding
      |
   LL |         GOOD => {}
      |         ~~~~

   Fix rust-lang#132582.
