to use the information in the module rather than TargetOptions. We've had and clang has used the use-soft-float attribute for some time now so have the backends set a subtarget feature based on a particular function now that subtargets are created based on functions and function attributes. For the one middle end soft float check go ahead and create an overloadable TargetLowering::useSoftFloat function that just checks the TargetSubtargetInfo in all cases. Also remove the command line option that hard codes whether or not soft-float is set by using the attribute for all of the target specific test cases - for the generic just go ahead and add the attribute in the one case that showed up. llvm-svn: 237079
