Niels Dossche 2c53d63197 Fix GH-10801: Named arguments in CTE functions cause a segfault 
Fixes GH-10801

Named arguments are not supported by the constant evaluation routine, in
the sense that they are ignored. This causes two issues:
  - It causes a crash because not all oplines belonging to the call are
    removed, which results in SEND_VA{L,R} which should've been removed.
  - It causes semantic issues (demonstrated in the test case).

This case never worked anyway, leading to crashes or incorrect behaviour,
so just prevent CTE of calls with named parameters for now.
We can choose to support it later, but introducing support for this in
a stable branch seems too dangerous.

This patch does not change the removal of SEND_* opcodes in remove_call
because the crash bug can't be triggered anymore with this patch as
there are no named parameters anymore and no variadic CTE functions
exist.

Closes GH-10811.

Niels Dossche 2e78c080c6 Improve the optimizer's check if a function is a prototype or not (#10467) 
Currently, a function is considered a prototype if the function is not
marked as final. However, a class marked as final also make it
impossible for a function to be overridden. Therefore, we know in this
case too that the function is not a prototype.
This allows the type inference algorithm to determine some types more
precisely, and can allow for more optimizations of the instructions.
Additionally, place some computation of the flags in their respective
blocks as a micro-optimization.

Note: anonymous classes *can* be extended (see test
Zend/tests/anon/011.phpt). Therefore we don't optimize this case.

Dmitry Stogov 567213c32a Drop range inference for IS_NULL/IS_FALSE/IS_TRUE. 
These values not always converted to IS_LONG (e.g. by -- and ++) and
this leads to incorrect range inferene and later to incorrect JIT code
generation.
