This commit implements the [wide-arithmetic] proposal which has recently reached phase 2 in the WebAssembly proposals process. The goal here is to implement support in LLVM for emitting these instructions which are gated behind a new feature flag by default. A new `wide-arithmetic` feature flag is introduced which gates these four new instructions from being emitted. Emission of each instruction itself is relatively simple given LLVM's preexisting lowering rules and infrastructure. The main gotcha is that due to the multi-result nature of all of these instructions it needed the lowerings to be implemented in C++ rather than in TableGen.
