// This test case tests the incremental compilation hash (ICH) implementation
// for enum definitions.
// 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.
// We also test the ICH for enum definitions exported in metadata. Same as
// above, we want to make sure that the change between rev1 and rev2 also
// results in a change of the ICH for the enum's metadata, and that it stays
// the same between rev2 and rev3.
