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.

Remove JMPZNZ opcode

While JMPZNZ can avoid execution of a separate JMP opcode in some
cases, it also prevents smart branch optimization, so creating
JMPZNZ may actually have a negative effect. It also adds additional
complexity for optimizations.

Drop JMPZNZ in favor of JMPZ+JMP or JMPNZ+JMP.

Remove special chr/count handling in sccp function evaluation

These can be handled by the generic code. Worth noting that count
will usually go through ZEND_COUNT, and chr on constants is
evaluated in the compiler, so these are not particularly compile-time
sensitive either.

Move FETCH_CLASS+INSTANCEOF special case out of update_op1_const()

Remove unnecessary INSTANCEOF special case in sccp

While we can't replace the instanceof operand, we will evaluate

case.

https://wiki.php.net/rfc/strtolower-ascii means that these functions no longer

evaluate at compile time.
