807e81937b Fix bug #72767 
The page size calculation did not account for the size of the
stack header (or rather it did account for it, but in the wrong
direction...)

ccf18da450 Eliminated checks for (func->op_array.fn_flags & ZEND_ACC_GENERATOR) in fast path of DO_FCALL* handlers. 
This slightly improves calls to regular function and method calls in cost of a bit slower generator initialization.
Separate call frame for generators, allocated on heap, now created by ZEND_GENERATOR_CREATE instruction.

6499162ff0 - get rid of EG(scope). zend_get_executed_scope() should be used instead. 
- ichanged zval_update_constant_ex(). Use IS_TYPE_IMMUTABLE flag on shared constants and AST, instead of "inline_change" parameter.

f484801483 Reduced amount of code generated for interrupt handling. 
Improved ZEND_VM_INTERRUPT_CHECK() placement (always perform checks after opcode handler completion, when instruction pointer value is alredy changed to the next opcode).

64f91774f2 Remove IS_VAR_RET_REF flag 
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.

a186ac0e47 IS_CONST operands don't have to be separated. Use reference-counting instead of duplication. 
- 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

7abfaac901 Merge zend_execute_data->called_scope into zend_execute_data->This. 
"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).
