op1 of ZEND_MATCH_ERROR, which refers to the match expression, is not freed by MATCH_ERROR itself. Instead, it is freed by ZEND_HANDLE_EXCEPTION. For normal control flow, a FREE is placed at the end of the match expression. Since FREE may appear after MATCH_ERROR in the opcode sequence, we need to correctly handle op1 of MATCH_ERROR as alive. Fixes GH-17106 Closes GH-17108
