This adds very basic support for module instantiation/allocation, as well as a stub for an interpreter (and executions APIs). The 'wasm' utility is further expanded to instantiate, and attempt executing the first non-imported function in the module. Note that as the execution is a stub, the expected result is a zero. Regardless, this will allow future commits to implement the JS WebAssembly API. :^)
