1. Cleaner assert_eq! & assert_ne! panic messages …

   Modify panic message for `assert_eq!`, `assert_ne!`, the currently unstable `assert_matches!`, as well as the corresponding `debug_assert_*` macros.
   
   ```rust
   assert_eq!(1 + 1, 3);
   assert_eq!(1 + 1, 3, "my custom message value={}!", 42);
   ```
   
   ```plain
   thread 'main' panicked at $DIR/main.rs:6:5:
   assertion failed: `(left == right)`
     left: `2`,
    right: `3`
   ```
   ```plain
   thread 'main' panicked at $DIR/main.rs:6:5:
   assertion failed: `(left == right)`
     left: `2`,
    right: `3`: my custom message value=42!
   ```
   
   ```plain
   thread 'main' panicked at $DIR/main.rs:6:5:
   assertion `left == right` failed
     left: 2
    right: 3
   ```
   
   ```plain
   thread 'main' panicked at $DIR/main.rs:6:5:
   assertion `left == right` failed: my custom message value=42!
     left: 2
    right: 3
   ```
   
   This PR is a simpler subset of the rust-lang#111030, but it does NOT stringify the original left and right source code assert expressions, thus should be faster to compile.
