Cacheline demote optimization for JITTed code is missing

[PeterYang12]

Description

Hi maintainers, This #11101 supports Cacheline demote and got merged in PHP-8.3.0.
I can see it:

$ git tag --contain 6bd5464
php-8.3.0RC1
php-8.3.0RC2
php-8.3.0RC3
php-8.3.0RC4
php-8.3.0RC5
php-8.3.0RC6
php-8.3.0alpha1
php-8.3.0alpha2
php-8.3.0alpha3
php-8.3.0beta1
php-8.3.0beta2
php-8.3.0beta3

However, in the latest codes, in the master branch, it's gone. And I can't find the implementation. For example, this fucntion https://github.com/php/php-src/blob/566100d7fef86e0061bad67f0ec56f659591bcc7/ext/opcache/jit/zend_jit_ir.c#L15741C53-L15741C53

Is there a specific reason why the optimization was removed, or was it accidentally removed during the process?
Given that the function lacks an implementation, it might fail to build on some machines.
If this task is still ongoing, our team would be very interested in participating or assisting with it.

Looking forward to your response :)

The support for CLDEMOTE was removed occasionally.

I've added support for CLDEMOTE in IR Framework via dstogov/ir@ed4fd9e and restored in php JIT via bf6b66f
