Export value/mask known bits from CCP.
Currently CCP throws away the known 1 bits because VRP and irange have
traditionally only had a way of tracking known 0s (set_nonzero_bits).
With the ability to keep all the known bits in the irange, we can now
save this between passes.
gcc/ChangeLog:
* tree-ssa-ccp.cc (ccp_finalize): Export value/mask known bits.
