o3 cpu: fix zero reg problem
There was an issue w/ the rename logic, which would assign a previous physical
register to the ZeroReg architectural register in x86. This issue was giving
problems for instructions squashed in threads w/ ID different from 0,
sometimes allowing non-mispredicted instructions to obtain a value different
from zero when reading the zeroReg.
