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.

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.

Remove asterix modifier (*) for generators

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).
