Comment (by bgamari):

 thoughtpolice correctly pointed out that in addition to implementing
 `mkJumpToAddr` we also need to ensure that the icache gets flushed after
 modifying the loaded code. I've added another patch to ensure this happens
 although this hasn't cleared up any further testsuite failures.

 These two patches brought down the number of total testsuite failures from
 204 to 104 in my test environment.
