Log Message:
Pull up revision 1.16 (requested by chs in ticket #1508):
change *_TLBUpdate for the MIPS3-style two-entry TLBs to only update existing
entries and not create new ones.  the problem with creating an entry is that
we only have the data for one side of the entry, so the other side could be
out of sync with the software PTEs, which the fault handlers are not prepared
to deal with.  fixes PR 14801.
