Quentin Colombet b51a68681a 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
coded) when optimizations apply.

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