I expect that indeed, the test case Kenner mentioned as motivation for the call
to mark_temp_addr_taken doesn't need it any more because of gimplification.
Any temporary that needs to live longer than a single gimple statement will be
represented in the gimple. So as he said, we should be able to do away with a
lot of the temporary management code.
