Sanjay Patel 351e1900a0 [SelectionDAG] change getConstant() to use the input SDLoc when building splat vectors ... The code change is simple enough: instead of attaching an anonymous SDLoc to splatted vector constants, use the scalar constant's existing SDLoc since that is what is passed into getConstant() as a param. But this changes instruction scheduling, so I'll explain why that happens. The motivation for this patch starts near: http://reviews.llvm.org/rL258833 ...x86's getZeroVector() could be similarly cleaned up and I thought it would be 'NFC'. But when I made that change locally, several x86 codegen tests wiggled. It turns out that the lack of SDLoc consistency in getConstant() changes the way ScheduleDAGRRList behaves. This is because the SDLoc contains 'IROrder' and some DAG scheduler algorithms use IROrder for tie-breaking.
