During SelectionDAG building explicitly set a node to constant zero when the
value is zero.
This allows optmizations to kick in more easily.
Fix some test cases so that they remain meaningful (i.e., not completely dead

<rdar://problem/14096009> superfluous multiply by high part of zero-extended
value.
