- with opcache all IS_CONST operands are not refcounted (scalars, interned strings or immutable arrays)
- without opcache IS_CONST operands are not shared between processes or threads and may use common reference counters
"called_scope" made sense only for static method calls, for dynamic calls it was always equal to the class of $this.
Now EG(This) may store IS_OBJECT + $this or IS_UNUSED + "called_scope" (of course, "called_scope" may be NULL).
Some code might need to be adopted to support this change.
Checks (Z_OBJ(EX(This))) might need to be converted into (Z_TYPE(EX(This)) == IS_OBJECT).

list() with keys (no foreach or tests)
This means we no longer allocate an unused VAR for the retval of
instructions that support unused results.
Nearly all instructions already used the result variable only if
it was used. The only exception to this was the return value
variable for internal function call results. I've adjusted the code
to use a stack zval for the unused return case now. As we have
retval specialization now, we know that it doesn't matter.
