412ad4b254 Uinified call frame handling for user and internal functions. 
Now EG(current_execute_data) always point to the call frame of the currently executed function.

47e85b1b35 Improve class constant fetch fix 
Dereference the cached constant for Test::TEST as well (and not just
self::TEST).

Also improve the phpt file to test this case as well - previously
this only manifested with opcache enabled, due to literal sharing.

Additionally the Z_TYPE_P != IS_REFERENCE assertion is now moved
into the TMP_VAR fetching code (as it applies to more than just
property assignments.)

d9a35c7e97 Fix class constant fetching 
If a class is extended after the constant fetch has been cached
the cached value will be turned into a reference. On the next
fetch the polymorphic cache will return this reference, which
will be directly returned. The object assignment code then
dereferences this result and performs a shallow copy, which is
invalid for references. This subsequently leads to the constant
value being prematurely freed.

This is fixed by dereferencing the value returned from the
polymorphic cache. Furthermore the incorrect dereference from
in the object assignment code is replaced with an assertion that
we're dealing with a non-reference, so ensure that this kind of
problem cannot go unnoticed in the future.

65f488ece3 Add STR_ALLOCA_* API, use in get_method and verify_arg 
This avoid unnecessary allocations when using dynamic method
dispatch and class typehints.

those just stood out for my usage.

f9927a6c97 Merge mainstream 'master' branch into refactoring 
During merge I had to revert:
	Nikita's patch for php_splice() (it probably needs to be applyed again)
	Bob Weinand's patches related to constant expression handling (we need to review them carefully)
	I also reverted all our attempts to support sapi/phpdbg (we didn't test it anyway)

Calls of such functiond that now accept cache_slot need to be changed to pass -1 instead of NULL.

31a2ac470c Fix argument unpacking across stack pages 
If multiple unpacks were used (or mixed with normal arguments)
parts of the arguments could land on different stack pages. If
this occurs the arguments will now be copied to a new stack page.

The code used to do this is copied verbatim from the PHP 5.4 branch
and only modified to reduce the amount of inlined code.

96b1c2145c Provide more macros for handling of interned strings 
* str_erealloc behaves like erealloc for normal strings, but will
   use emalloc+memcpy for interned strings.
 * str_estrndup behaves like estrndup for normal strings, but will
   not copy interned strings.
 * str_strndup behaves like zend_strndup for normal strings, but
   will not copy interned strings.
 * str_efree_rel behaves like efree_rel for normal strings, but
   will not free interned strings.
 * str_hash will return INTERNED_HASH for interned strings and
   compute it using zend_hash_func for normal strings.

0856714576 Always pass return_value_ptr to internal functions 
Previous some places passed return_value_ptr only if the function
returned by reference. Now return_value_ptr is always set, even
for functions returning by-value.

This allows you to return zvals without copying their contents. For
this purpose two new macros RETVAL_ZVAL_FAST and RETURN_ZVAL_FAST
are added:

    RETVAL_ZVAL_FAST(zv); /* Analog to RETVAL_ZVAL(zv, 1, 0) */
    RETURN_ZVAL_FAST(zv); /* Analog to RETURN_ZVAL(zv, 1, 0) */

These macros behave similarly to the non-FAST versions with
copy=1 and dtor=0, with the difference that the FAST versions
will try return the zval without copying by utilizing return_value_ptr.

70f83f35d0 . The VM stacks for passing function arguments and syntaticaly nested calls were merged into a single stack. The stack size needed for op_array execution is calculated at compile time and preallocated at once. As result all the stack push operatins don't require checks for stack overflow any more. 
. Generators implementation was improved using the new VM stack. Now it's a bit more clear and faster.
