Comment:

 The native codegen, LLVM backend, unreg backend, and this JS codegen, all
 have an interface that is roughly of the form
 {{{
 someCodeGen :: DynFlags -> FilePath -> Stream IO RawCmmGroup () -> IO ()
 }}}
 which might suggest that we could make them separate packages, and have
 some sort of plugin system. However, I'm not sure if this would really buy
 us anything: A new backend is likely to need to alter `DynFlags` too, and
 may also need other changes around the compiler. I think most of the
 backends export some other functions too, although I don't know what for
 OTTOMH.

 My gut feeling is that it's too early to merge this into GHC: Let's wait a
 while and see which of the 3 JS approaches turns out to be the most
 fruitful.
