Include '.test' suffix in target specific lit configs that need it

Apparently my final cleanup to use a relevant suffix for these tests before
committing r176831 caused them to stop running since lit wasn't configured to
run tests with that suffix in those directories (why don't we just have a
global suffix list?). So, add the suffix to the relevant directories & fix the
test that has bitrotted over the last week due to my debug info schema changes.

TableGen fix for the new machine model.

Properly handle cases where a group of instructions have different
SchedRW lists with the same itinerary class.
This was supposed to work, but I left in an early break.
