    [wasm] Support validation of asm.js modules with != 3 args.
    
    Our previous per-arch instantiation thunks for asm.js
    didn't support modules that had or were called with anything other
    than 3 arguments. Adding support for this.
    
    Addding a runtime test method to check if asm validation succeeded.
    
    Adding a test of validation with different argument count combinations.
