LLVM backend for 6502
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.
