Suggest parentheses when `match` or `if` expression in binop is parsed as statement

```
error[E0308]: mismatched types
  --> $DIR/expr-as-stmt.rs:81:5
   |
LL |     match () { _ => true } && match () { _ => true };
   |     ^^^^^^^^^^^^^^^^^^^^^^ expected `()`, found `bool`
   |
help: parentheses are required to parse this as an expression
   |
LL |     (match () { _ => true }) && match () { _ => true };
   |     +                      +
```

Address the common case from rust-lang#88727. The original parse error is still outstanding, but the cases brought up in the thread are resolved.
