Optimize some usages of !! and -- in suggestions (#15366)
When an expression is made of a `!` or `-` unary operator which does not
change the type of the expression, use a new variant in `Sugg` to denote
it. This allows replacing an extra application of the same operator by
the removal of the original operator instead.

Some suggestions will now be shown as `x` instead of `!!x`. Right now,
no suggestion seems to produce `--x`.
