30f1b17262 Fix null check in sccp add_array_elem chain handling 
We need to check result_use rather than result_def for a null zval.
Previously we were later assuming that the null zval is really a
partial array, which does not go well.

Don't try to evaluate various operations with partial array operands.
We could evaluate some of these, but let's be conservative for now...

twice.

a50198d0fe Implement ??= operator 
RFC: https://wiki.php.net/rfc/null_coalesce_equal_operator

$a ??= $b is $a ?? ($a = $b), with the difference that $a is only
evaluated once, to the degree that this is possible. In particular
in $a[foo()] ?? $b function foo() is only ever called once.
However, the variable access themselves will be reevaluated.

3269e88468 Implement single-pass live range calculation 
Instead of interleaving creation of live-ranges with the main
compiler code, compute them in a separate pass over the opcodes
as part of pass_two. Additionally, do not keep live ranges
synchronized during optimization in opcache and instead use the
same mechanism to recompute them after optimization.
