GET_OP1_OBJ_ZVAL_PTR_DEREF does not actually DEREF

[TimWolla]

Description

The following code:

ZEND_VM_COLD_CONST_HANDLER(110, ZEND_CLONE, ANY, ANY)
// …
	obj = GET_OP1_OBJ_ZVAL_PTR_DEREF(BP_VAR_R);
	ZEND_ASSERT(!Z_ISREF_P(obj));

Resulted in this output:

php: Zend/zend_vm_execute.h:2812: const zend_op *ZEND_CLONE_SPEC_HANDLER(zend_execute_data *, const zend_op *): Assertion `!(zval_get_type(&(*(obj))) == 10)' failed.

But I expected this output instead:

No assertion failure

Found as part of the clone-with work, while investigating whether or not the current OPcode specialization for ZEND_CLONE is meaningful or not. A specialized handler for CONST likely is not necessary, since object literals are not a thing.
