This changes adds shadow and origin propagation for unknown intrinsics by examining the arguments and ModRef behaviour. For now, only 3 classes of intrinsics are handled: - those that look like simple SIMD store - those that look like simple SIMD load - those that don't have memory effects and look like arithmetic/logic/whatever operation on simple types. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170530 91177308-0d34-0410-b5e6-96231b3b80d8
