Generatirs are going to be used less than regular functions

Slight performance improvement

Moved zend_create_execute_data_from_op_array() implementation from zend_vm_execute.skl to zend_execute.c

Optimized access to temporary and compiled VM variables

. 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 preallocate

. 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.

Improved "finally" im[plementation

Fixed bug #63428 (The behavior of execute() changed)

Use zend_execute_internal always to call internal functions

Fix bug #63173: Crash when invoking invalid array callback

The code did not check whether the zend_hash_index_find calls succeded,
so PHP crashed when an array callback was called that c

which don't have the indices 0 and 1.

Fix invalid read / remove useless code

Generators follow a different cleanup path, so the extra check for freeing
the execute_data is unnecessary there. It actually caused problems because
op_array->fn_flags could be in freed memory at that time (in case op_array
came from a closure in an ArrayAccess container).

This fixes the valgrind warning in Zend/tests/bug54367.phpt.

Fix leak when yielding array as key

The code was copy-pasted and I forgot to change OP1 to OP2 in that one
place.

Remove implementation stubs for yield delegation

I decided to leave out yield delegation for an initial proposal, so remove
the stubs for it too.

Fix several issues and allow rewind only at/before first yield

* Trying to resume a generator while it is already running now throws a
fatal error.
* Trying to use yield in fina

Fix several issues and allow rewind only at/before first yield

* Trying to resume a generator while it is already running now throws a
fatal error.
* Trying to use yield in finally while the generator is being force-closed
(by GC) throws a fatal error.
* Rewinding after the first yield now throws an Exception

Prefer no finally block for most situations

Add dedicated opcode for returns from a generator

Generators don't have a return value, so it doesn't make sense to have
a shared implementation here.

Fixed bug that jmp in try block jmp over finally block

Refactor the implemention, make codes clear

stash

Make the codes clearer, and also check continue statement

Add functions declarations, use tabs

fix windows build

Support trivial finally in generators (no yield, no return)

The finally clause is now properly run when an exception is thrown in the
try-block. It is not yet run on `return` and also no

Support trivial finally in generators (no yield, no return)

The finally clause is now properly run when an exception is thrown in the
try-block. It is not yet run on `return` and also not run when the generator
is claused within a try block.

I'll add those two things as soon as laruence refactored the finally code.

Fixed bug #62653: (unset($array[$float]) causes a crash)

the reason why jpauli and I can not reproduce is (it's silly):
I typo "USE_ZEND_ALLOC *&&* valgrind" at the first time, then I always ctrl+r
and jpauli copied my command from the pastbin :)
