Lower the call to 'memset' intrinsic function into a series of store operations.
| DAG | Selection DAG where lowered code is placed. |
| dl | Link to corresponding IR location. |
| Chain | Control flow dependency. |
| Dst | Pointer to destination memory location. |
| Src | Value of byte to write into the memory. |
| Size | Number of bytes to write. |
| Align | Alignment of the destination in bytes. |
| isVol | True if destination is volatile. |
| DstPtrInfo | IR information on the memory pointer. |
The function tries to replace 'llvm.memset' intrinsic with several store operations and value calculation code. This is usually profitable for small memory size.
