Optimize away invoke_ calls where possible (#2442)
When we see invoke_ calls in emscripten-generated code, we know
they call into JS just to do a try-catch for exceptions. If the target being
called cannot throw, which we check in a whole-program manner, then
we can simply skip the invoke.
I confirmed that this fixes the regression in emscripten-core/emscripten#9817 (comment)
(that is, with this optimization, upstream is around as fast as fastcomp).
When we have native wasm exception handling, this can be
extended to optimize that as well.
