Looking at the variable names I wonder if it's a case of no longer loosing the
wrap flags rather than gaining them? From `CodeGenFunction::EmitSMELd1St1`:
```
llvm::Value *StreamingVectorLengthCall =
Builder.CreateMul(Builder.CreateCall(StreamingVectorLength),
llvm::ConstantInt::get(Int64Ty, 8), "svl",
/* HasNUW */ true, /* HasNSW */ true);
llvm::Value *Mulvl =
Builder.CreateMul(StreamingVectorLengthCall, Ops[4], "mulvl");
```
