Add target to use LLVM wasm backend
The new target is wasm32-experimental-emscripten. Adds a new configuration option to opt in to building experimental LLVM backends such as the WebAssembly backend. The target name was chosen to be similar to the existing wasm32-unknown-emscripten target so that the build and tests would work with minimal other code changes. When/if the new target replaces the old target, simply renaming it should just work.
