Simplify hoisting of array/slice patterns
We can replace some tricky iterator-mutation code with a much simpler version that uses `while let` to shrink a slice. We also check whether a subpattern would be a wildcard _before_ hoisting it, which will be very useful when trying to get rid of `print::PatKind` later.
