In which we add a new code generator to the Glasgow Haskell
Compiler. This codegen supports ELF and Mach-O targets, thus covering
Linux, macOS, and BSDs in principle.  It was tested only on macOS and
Linux.  The NCG follows a similar structure as the other native code
generators we already have, and should therfore be realtively easy to
follow.

It supports most of the features required for a proper native code
generator, but does not claim to be perfect or fully optimised.  There
are still opportunities for optimisations.
