  1. Add implicit wasm feature disabling based on min browser versions 

    llvm and binaryen now default to enabling sign-ext and mutable-globals
by default. See https://reviews.llvm.org/D125728.

In order to allow users to continue to target older browsers we will
now lower sign-ext operations in a binaryen pass if the target browsers
don't support it.
