Sanjay Patel 89305e5345 Don't prevent a vselect of constants from becoming a single load (PR20648).
Fix for PR20648 - http://llvm.org/bugs/show_bug.cgi?id=20648

This patch checks the operands of a vselect to see if all values are constants.
If yes, bail out of any further attempts to create a blend or shuffle because
SelectionDAGLegalize knows how to turn this kind of vselect into a single load.

This already happens for machines without SSE4.1, so the added checks just send
more targets down that path.
