* Backport r69961 to trunk, replacing JUMP_IF_{TRUE,FALSE} withJeffrey Yasskin2009-02-284-106/+164
| | | | | | 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.
* Issue 5176: special-case string formatting in BINARY_MODULO implementation. ↵Collin Winter2009-02-201-1/+4
