cpu: Fix BTB threading oversight
The BTB doesn't hash on the thread id but does check the
thread id for 'btb hits'. This resulted in 1-thread of a multi-threaded
workload taking a BTB entry, and all other threads missing for the same branch
missing. Probably wasn't so horrific for multi-programmed SPEC.
