1 // IM has the following fastpaths:
2 // - constant index (constant)
3 // - need negative int check (neg)
4 // - needs hole check (hole)
5 // So to test everything we have to do:
6 // constant | neg | hole
7 // test 1: 0 0 0
8 // test 2: 1 0 0
9 // test 3: 0 1 0
10 // test 4: 1 1 0
11 // test 5: 0 0 1
12 // test 6: 1 0 1
13 // test 7: 0 1 1
14 // test 8: 1 1 1
