Assume the following sequence:
pitlbe r0(sr0,r0)
iitlba r4,(sr0,r0)
ldil L%3000000,r5
iitlbp r5,(sr0,r0)
This will purge the whole TLB and add an entry for page 0. However
the current TLB implementation in helper_iitlba() will store to
the last empty TLB entry, while helper_iitlbp() will write to the
first empty entry. That is because an empty entry will match address
0 in helper_iitlba()
