[wasm] Simd128 types should not be available in asmjs modules. 

 - Added gating code in the module-decoder to allow SIMD code only when
 it can be decoded correctly
 - SIMD128 values should not be exported to JS
 - Try/Catch should not be available in asmjs modules
 - Trivial fixes for S128  values
