Dmitry Stogov 5ee8413259 Fixed bug #62210 (Exceptions can leak temporary variables. As a part of the fix serious refactoring was done. op_array->brk_cont_array was removed, and replaced with more general and speed efficient op_array->T_liveliness. ZEND_GOTO opcode is always replaced by ZEND_JMP at compile time). (Bob, Dmitry, Laruence)

    Improved algorithm. It's actually the same algorithm with second loop removed and simpler temporary data structures. The only difference may be in "re-defined" vatriable handling. Now live-range in that case started from the seconnd definition (this must be more safe).
