This more completely hides them from LSR, which isn't usually able to do anything meaningful with non-affine expressions anyway, and this consequently hides them from SCEVExpander, which is acutely unprepared for non-affine expressions. Replace test/CodeGen/X86/lsr-nonaffine.ll with a new test that tests the new behavior. This works around the bug in PR10117 / rdar://problem/9633149, and is generally an improvement besides. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134268 91177308-0d34-0410-b5e6-96231b3b80d8

Standardize on two preferred entrypoints: one that takes a StructType and ArrayRef, and one that takes StructType and varargs. In cases where there isn't a struct type convenient, we now add a ConstantStruct::getAnon method (whose name will make more sense after a few more patches land). It would be "really really nice" if the ConstantStruct::get and ConstantVector::get methods didn't make temporary std::vectors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133412 91177308-0d34-0410-b5e6-96231b3b80d8
