Jeffrey Yasskin 68d6852006 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.
