[Mono-list] Mono LLVM

[Rodrigo Kumpera]

This was a bug on the last released mono and we've fixed it.

Besides that, no, it's not possible to use emscripten with mono's llvm
output for a lot of reasons.
The output embeds calls to the mono runtime and some trampilines.
Mono use a custom LLVM with custom IR operations and that won't work
on emscripten
without some work on their end.
