  [Tests] Add test coverage for prefix selection logic

Note that I'm not asserting this code is correct; I'm simply adding coverage for what's there already.  I'm reasonable sure the logic works for existing relaxable instructions, but I wouldn't be suprised if there were incorrect cases for other instructions.  (i.e. is it legal to add prefixes to all instructions?)
