So I'm not super-familiar with exactly how emscripten uses LLVM's LTO feature, but LTO is definitely a use case that is supported by upstream, as long as we use it in a way similar to what they expect. PNaCl always uses LTO (when optimizations are enabled) and the issues we've had with it (which have been minor) have mostly just stemmed from those divergences (e.g. including libc in the optimization, which LLVM's LTO doesn't do by default).
