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.
