As far as I can discern these are leftovers of the interactive
shell implementation that was used before PHP 5.4. Now the readline
ext makes use of normal eval calls for this.
So, dropping these until there is evidence to the contrary, as they
currently wouldn't work anyway.

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.)
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.
This avoid unnecessary allocations when using dynamic method
dispatch and class typehints.
Probably there are other places where this should be done as well,
those just stood out for my usage.
It should be accessed using Z_CACHE_SLOT() macro.
zend_literal structure is removed.
API functions that accepted pointer to zend_literal now accept pointer to zval or cache_slot directly.
Calls of such functiond that now accept cache_slot need to be changed to pass -1 instead of NULL.
This might cause passing invalid pointer if the array could be resized before IS_INDIRECT usage.
Now we use IS_REFERENCE instead of IS_INDIRECT.
The following test crashed before:
<?php $a = array(0,1,2,3,4,5,6,7); $a[8] = &$a[7]; ?>
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.

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.
This is just an intial merge. It does not yet make generators and finally
work together.

To make the generator function show up in backtraces one has to insert an
additional execute_data into the chain, as prev_execute_data->function_state
is used to determine the called function.
Adding the additional stack frame is also required for func_get_args(), as
the arguments are fetched from there too. The arguments have to be copied
in order to keep them around. Due to the way they are saved doing so is
quite ugly, so I added another function zend_copy_arguments to zend_execute.c
which handles this.
To keep things clean two new functions are introduced:
zend_clean_and_cache_symbol_table(HashTable *symbol_table)
zend_free_compiled_variables(zval ***CVs, int num)

Since we can't break BC completely (yet) lets bump this from E_STRICT.
Also added a new section to UPGRADING for engine changes.

ZEND_ACC_PASS_REST_BY_REFERENCE in zend_function.fn_flags
. zend_function.return_reference is replaced by ZEND_ACC_RETURN_REFERENCE
in zend_function.fn_flags
. zend_arg_info.required_num_args removed. it was needed only for internal
functions. Now the first arg_info for internal function (which has special
meaning) is represented by zend_internal_function_info structure.
. zend_op_array.size, size_var, size_literal, current_brk_cont,
backpatch_count moved into CG(context), because they are used only during
compilation.
. zend_op_array.start_op is moved into EG(start_op), because it's used
only for 'interactive' execution of single top-level op-array.
. zend_op_array.done_pass_two is replaced by ZEND_ACC_DONE_PASS_TWO in
zend_op_array.fn_flags.
. op_array.vars array is trimmed (reallocated) during pass_two.
. zend_class_entry.constants_updated is replaced by
ZEND_ACC_CONSTANTS_UPDATED in zend_class_entry.ce_flags
. the size of zend_class_entry is reduced by sharing the same memory space
by different information for internal and user classes.
See zend_class_inttry.info union.
. ZEND_RECV now always has IS_CV as its result
. ZEND_CATCH now has to be used only with constant class names
. ZEND_FETCH_DIM_? may fetch array and dimension operans in a different order
Restored double->long conversion behavior to that of PHP 5.2 (on most platforms) and prior:
* Out-of-range numbers overflow/preserve least significant bits (no LONG_MAX/MIN limit)
* See bug #42868 (presumably-rare platform with different results in 5.2)
* On 32-bit platforms with 64-bit long type, a zend_long64 cast has been added,
otherwise it's the same as 5.2
* Use this conversion method everywhere instead of some plain (long) casts
Added 'L' parameter parsing specifier to ensure a LONG_MAX/MIN limit:
* Essentially what 5.3's new conversion was doing in most cases
* Functions with "limit" or "length" type params could be updated to use this,
and prevent confusing overflow behavior with huge numbers (*also* in 5.2)
- See bug #47854, for example; or even #42868 again
