WebPrims IR is a set of primitive operators that can be used to compose other operators. Prims IR is a lower level opset than core aten IR, and it further decomposes ops into explicit type promotion and broadcasting ops: prims.convert_element_type and prims.broadcast_in_dim. This opset is designed to interface with compiler backends.
