[M3devel] multi-threaded m3front?

In my informal observation, it is additionally true that:

     gcc compiling m3cc is quite a bit slower than cm3 with m3cc backend.
     gcc compiling llvm/clang is a lot slower than that.
     clang compiling individual C++ units is noticeably slower than gcc
       on the same units.


All of which is leading to my feeling that compiling Modula-3 code is already
so much faster than compiling C or C++, that it's a pretty minor need to
speed it up even more.
