Add compilation to NodeJS module #111

I guess it was an accident that you checked in the build outputs? |
I did it to share the output with @pgherveou |

Sorry I still don't understand what we need it for. Don't we build LLVM completely from source with emscripten? What is this binary version needed for? Shouldn't the emscripten build version be used for everything?

We need the RISC-V compiler-rt and also we compile some shared code (for example our "stdlib") into LLVM bitcode at this stage. Those bitcodes are bundled with the compiler and just linked into into contract code. The emscripten version does compile contract code but not those things.

These crates are compiled on the host to the RISC-V target, to be linked into the contract binary when it is built using the WASM version of revive.
Cross-compile the
resolcbinary to WebAssembly (WASM) using Emscripten.
