Alkis Evlogimenos 1dd872ce94 Move machine code rewriter and spiller outside the register
allocator.

The implementation is completely rewritten and now employs several
optimizations not exercised before. For example for 164.gzip we have
997 loads and 699 stores vs the 1221 loads and 880 stores we have
before.
