David Sherwood 69b39e7cc7 [SelectionDAG] Add support for extending masked loads in computeKnownBits (#115450) ...

We already support computing known bits for extending loads, but not for
masked loads. For now I've only added support for zero-extends because
that's the only thing currently tested. Even when the passthru value is
poison we still know the top X bits are zero.
