"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).

Warn on non-/bad numeric strings in arithmetic
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.
This opcodes inserts a local CV into the closure static variable
table. This replaces the previous mechanism of having static
variables marked as LEXICAL, which perform a symtable lookup
during copying.
This means a) functions which contain closures no longer have to
rebuild their symtable (better performance) and b) we can now track
used variables in SSA.

Refactored immplementation of https://wiki.php.net/rfc/class_const_visibility
@reeze created an RFC here and I emailed internals here and didn't get any responses positive/negative.
Move zend_op_array->brk_cont_array into CG(context).brk_cont_array.
Use more compact zend_op_array->live_range instead of zend_op_array->brk_cont_array.
Semantic is kept unchanged.
This additionally removes support for binding to an unknown (not in parent hierarchy) scope.
Removing support for cross-scope is necessary for certain compile-time assumptions (like class constants) to prevent unexpected results
We didn't have zend_internal_function.reserved[] in PHP5, but we always allocated space for zend_function union, and extensions were able to reuse zend_function.op_array.reserved[] even for internal function. Now this is not possible. And extensions have to use zend_function.op_array.reserved[] for user functions and zend_function.internal_function.reserved[] for internal.
Revert "We cannot safely assume that all op array will be refcount 0 after execution"
This reverts commit b6936adb58.
This change turns out to not have been a clever idea and was causing more weirdness than it helped...
This was generated for a return from a try block with both a catch
and a finally. However at this point no exception can be active,
because it either didn't exist in the first place or was explicitly
discarded using DISCARD_EXCEPTION.
