1e9a5c67ef Rename standard array function parameters to $array 
This is targeting 8.0.

`$arg` seems like a poor choice of a name,
especially if the function were to have arguments added.

In many cases, the php.net documentation already has $array for these functions.
E.g. https://www.php.net/manual/en/function.array-intersect.php

I'd assume that since named arguments was added to 8.0 near the feature freeze,
PHP's maintainers had planned to make the names consistent
and gradually use the same name for  docs and implementation.

f491dabe40 Fix nullsafe operator on reference 
Dereference the value before checking the type. As the happy path
necessarily has to check for references, I'm not bothering to
delay the comparison.

ee7eecf321 Fix leak with nullsafe operator with constant LHS 
Followup to 5303bcdd32. We need to
perform the addref after emitting the opline, because that might
intern the string.

Fixes oss-fuzz #24479.
