160ec0d9cc COME_FROM for 3.x POP_EXCEPT, DRY with op_name() ... 
Start adding COME_FROMs for POP_EXCEPT in preparation for
getting tryelse blocks correct.

Simpler opname access functions:
  - self.op_name(op) is self.opc.opname[op]
  - self.op_name_from_offset(offset) is self.opc.opname[self.code[offset]]

verify.py: not all offsets are ints

1cb2cd7a82 More 2.6, 2.7 control flow 
Todo more COME_FROMs but now need to check targets better. In some cases
we're relying on grammar ambiguity to work out right and in 2.7 it doesn't

9ec312ba5e More 2.6, 2.7 control-flow bugs 
Wasn't limiting exception clause to try finally. Probably still has bugs
in try-finally nesting

Add another 2.6/2.7 COME_FROM to try to limit if/end scope better
