Simplify lifetimes by allocating patterns on the arena

We want the lifetimes of the patterns contained in the matrix and the
candidate `PatStack` to be the same so that they can be mixed together.
A lot of this would not be necessary if `SmallVec` was covariant in its
type argument (see https://github.com/servo/rust-smallvec/issues/146).
