This is a second attempt at landing CL 644866 which was reverted by CL 667019. Extends the current implementation of WASM exceptions to be able to throw exceptions with values (not just tags). A JS typed (uint_16) array is used to hold the thrown values. This allows all WASM types to be stored (i32, i64, f32, and f64) as well as be inspected in JS. The previous CL was reverted because the WASM compiler made calls to run time functions with tagged objects, which must not be done. To fix this, all run time calls use the thread-level isolate to hold the exception being processed.
