Use a bigger hammer to fix PR11314 by disabling the "forcing two-address
instruction lower optimization" in the pre-RA scheduler.

The optimization, rather the hack, was done before MI use-list was available.
Now we should be able to implement it in a better way, perhaps in the
two-address pass until a MI scheduler is available.

Now that the scheduler has to backtrack to handle call sequences. Adding
artificial scheduling constraints is just not safe. Furthermore, the hack
is not taking all the other scheduling decisions into consideration so it's just

Track reference count independently from clear().

This allows clear() to be called on a DomainValue with references.

Handle reference counts in one function: release().

This new function will decrement the reference count, and collapse a
domain value when the last reference is gone.

This simplifies DomainValue reference counting, and decouples it from
the LiveRegs array.

these artificial dependencies can get tied up in calling seqeunce
