Ingvar Stepanyan 7da3f07333 Switch to Emscripten upstream
Looks like we've been stuck on Emscripten fastcomp backend, misssing out on all new optimisations between LLVM 6 and LLVM 11 and going via slow asm.js pipeline when building.

This changes Docker images for Emscripten projects to point to emscripten-upstream instead and commits the updated artifacts.
