Ok, I had one regression and that was caused by a TImode load that was at the
end of the valid offset range...meaning "addr" was ok for a offset address, but
we could not add one more offset, which is what offsettable_address_p() tests
for.  Looks like I just need to replace offsettable_address_p() with
rs6000_offsettable_memref_p().  That fixes the failing test case.  I'll
rebootstrap/regtest with that change.
