Comment #1 on issue 3907 by [email protected]: Allowing asm.js memory
growth causes big slowdown
https://code.google.com/p/v8/issues/detail?id=3907
Well, the changes are everything but minor. Allowing memory growth makes
immutable context slots mutable (the typed arrays actually), which means
that TurboFan cannot treat them as constants. Not only does this defeat
several optimizations in V8, Emscripten also generates invalid asm.js with
this option so it'll probably also affect other browsers that support
asm.js.
