7ba3e69a - [SelectionDAG][X86] Remove unused elements from atomic vector.

[SelectionDAG][X86] Remove unused elements from atomic vector. After splitting, all elements are created. The two components must be found by looking at the upper and lower half of the value. This change extends EltsFromConsecutiveLoads to understand AtomicSDNode so that unused elements can be removed. commit-id:b83937a8
