arch-gcn3: convert vALU instruction counters from 32 to 64-bit

The vALU instruction counters were previously 32 bits, but for some
workloads this value wraps around and triggers an assert failure
because the max vALU operations are reached.  To resolve this, this
commit increases the counter size to 64 bits.
