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.

work together.

80d5ae3cea Implemented 'finally' keywords for php
RFC: https://wiki.php.net/rfc/finally
FR: https://bugs.php.net/bug.php?id=32100
and I have got some improvment ideas(performance), will implemented
later. thanks

c9709bfbd7 Remove asterix modifier (*) for generators
Generators are now automatically detected by the presence of a `yield`
expression in their body.

This removes the ZEND_SUSPEND_AND_RETURN_GENERATOR opcode. Instead
additional checks for ZEND_ACC_GENERATOR are added to the fcall_common
helper and zend_call_function.

This also adds a new function zend_generator_create_zval, which handles
the actual creation of the generator zval from an op array.

I feel like I should deglobalize the zend_create_execute_data_from_op_array
code a bit. It currently changes EG(current_execute_data) and
EG(opline_ptr) which is somewhat confusing (given the name).

f627be5254 Add support for executing a zend_execute_data
This adds another function execute_ex(), which accepts a zend_execute_data
struct to run (contrary to execute(), which accepts a zend_op_array from
which it initialized the execute_data).

This needs a bit more cleanup.

5e763d9420 Allocate execute_data using malloc for generators
Generators need to switch the execute_data very often. If the execute_data
is allocated on the VM stack this operation would require to always copy
the structure (which is quite large). That's why the execution context is
allocated on the heap instead (only for generators obviously).

f2df6a4a3e - Improved memory usage
. zend_function.pass_rest_by_reference is replaced by
    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.

453b49ed20 Added a number of small performance tweaks and optimizations
. 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
