Is it possible to embed llvm into the v8 engine? If so, all we need to do is to compile c/c++ codes into llvm byte codes, then import it as js modules, like this: `import {LibSass} from './libsass.bin'`.

It's a little boring to see 'tb_*' wrappers such as 'tb_void_t', why not the standard way? Also I don't like xmake compares to premake.
