 Backport r69961 to trunk, replacing JUMP_IF_{TRUE,FALSE} with
 POP_JUMP_IF_{TRUE,FALSE} and JUMP_IF_{TRUE,FALSE}_OR_POP. This avoids executing
 a POP_TOP on each conditional and sometimes allows the peephole optimizer to
 skip a JUMP_ABSOLUTE entirely. It speeds up list comprehensions significantly.
