Summary:
Optimization passes may remove llvm.coro.suspend intrinsic while leaving matching llvm.coro.save intrinsic orphaned.
Make sure we clean up orphaned coro.saves. The bug manifested with a crash similar to this:
```
llvm_unreachable("Unknown type!");
llvm::MVT::getVT (Ty=0x489518, HandleUnknown=false)
llvm::EVT::getEVT
llvm::TargetLoweringBase::getValueType
llvm::ComputeValueVTs
llvm::SelectionDAGBuilder::visitTargetIntrinsic
```
