legality of an address mode to not use a struct of four values and instead to accept them as parameters. I'd love to have named parameters here as most callers only care about one or two of these, but the defaults aren't terribly scary to write out. That said, there is no real impact of this as the passes aren't yet using STTI for this and are still relying upon TargetLowering. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171595 91177308-0d34-0410-b5e6-96231b3b80d8
