A new pass DXILOpLowering was added. It will scan all llvm intrinsics, create dxil op function if it can map to dxil op function. Then translate call instructions on the intrinsic into call on dxil op function. dxil op function will add i32 argument to the begining of args for dxil opcode. So cannot use setCalledFunction to update the call instruction on intrinsic. This commit only support sin to start the work.
