wasm2js: more js optimization (#2050)
* Emit ints as signed, so -1 isn't a big unsigned number. * x - -c (where c is a constant) is larger than x + c in js (but not wasm) * +(+x) => +x * Avoid unnecessary coercions on calls, return, load, etc. - we just need coercions when entering or exiting "wasm" (not internally), and on actual operations that need them.
