We don't want ReflectionMethod::invoke() to simply ignore its first argument,
if the method to invoke is a static method. Instead we match its ZPP with
that of ReflectionMethod::invokeArgs(). Furthermore, we apply the DRY
principle by factoring out the code to a common helper function to prevent
inadvertent future divergence of the implementations of both methods.
As can be seen from the necessity to adapt some test cases, this causes a
BC break for some pathological cases. Therefore we apply this patch to PHP
7.1 only, which is still in beta phase.
In a1c405e0c5 next to the actual fix
I have also switched some (effective) ZVAL_DUPs to ZVAL_COPYs. I'm
reverting this part as those were probably there for a reason
(presumably issues with non-atomic refcounting on ZTS).
Instead decide whether a function returned by reference or by value
by checking whether the return value has REFERENCE type. This means
that functions returning by reference must always return a reference
and functions returning by value must not return a reference.
"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).

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.
Summary:
The compiler complains and raised some warnings about boolean
conversion:
warning: address of 'ce->constants_table' will always evaluate to
'true' [-Wpointer-bool-conversion]
Since the address of 'HashTable' will always evaluate to true. the
condition should be removed. The scope is kept for local variables.
Platform:
OS X 10.11
Compiler:
Apple LLVM version 7.0.0 (clang-700.0.72)
Target: x86_64-apple-darwin15.0.0
Thread model: posix
This prevented compilation warnings and disclosed few incorrect usages in Zend/zend_vm_def.h and ext/dom/xpath.c.
Now explicit type casting may be required on call site.
This may break some C extension code, but it shoulfn't be a problem to add explicit casting.
