This implements a basic version of the algorithm from: Luc Maranget, [Compiling pattern matching to good decision trees](http://moscova.inria.fr/~maranget/papers/ml05e-maranget.pdf). No heuristics are used - the first column is always chosen. * Closes #1798 * Closes #1225 * Closes #1926 * Adds a global `--no-coverage` option which turns off coverage checking in favour of generating runtime failures * Changes the representation of Match patterns in JuvixCore to achieve a more streamlined implementation * Adds options to the Core pipeline
