BasicTTI::getMemoryOpCost must explicitly check for non-simple types; setting AllowUnknown=true with TLI->getSimpleValueType is not sufficient because, for example, non-power-of-two vector types return non-simple EVTs (not MVT::Other). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206150 91177308-0d34-0410-b5e6-96231b3b80d8
