Fix ARM mode bustage that occurred during lockdown
- At some point, the order of arguments to InterpOne got switched
around for no apparent reason in the refcount optimization diff.
- My fix to poly-torture.php got accidentally pseudo-reverted, also in
the refcount optimization diff.
- The type effects of an interped PushL wasn't accounted for properly.
There are still a few more quick tests that crash. Based on their file
names, I think it's all a single root cause. I'll look at those next.
