In mips3_TBIS(va) do not invalidate the other half of the JTLB entry if
the page is wired down. Flushing both halves of a wired TLB entry resulted
in hangs when in programs called for and released kernel memory
soon after being invoked. In particular, we see this when single-stepping
a process using GDB.
It would be better if we could arrange to use both halves of the TLB
entry for the PCB, but for some reason we frequently end up with things
on an odd page boundary.
