Summary: The framework for supporting target-specific MachineFunctionInfo was added in r356215. This adds serialization support for WebAssemblyFunctionInfo on top of that. This patch only adds the framework and does not actually serialize anything at this point; we have to add YAML mapping later for the fields in WebAssemblyFunctionInfo we want to serialize if necessary.
