[DAG] visitFREEZE - replace multiple frozen/unfrozen uses of an SDValue with just the frozen node (#150017 )

Similar to InstCombinerImpl::freezeOtherUses, attempt to ensure that we
merge multiple frozen/unfrozen uses of a SDValue. This fixes a number of
hasOneUse() problems when trying to push FREEZE nodes through the DAG.

Remove SimplifyMultipleUseDemandedBits handling of FREEZE nodes as we
now want to keep the common node, and not bypass for some nodes just
because of DemandedElts.

Fixes #149799
