// This test case tests the incremental compilation hash (ICH) implementation
// for match expressions.
// The general pattern followed here is: Change one thing between rev1 and rev2
// and make sure that the hash has changed, then change nothing between rev2 and
// rev3 and make sure that the hash has not changed.
//@ build-pass (FIXME(62277): could be check-pass?)
