Subzero: Use the linear-scan register allocator for Om1 as well. This removes the need for Om1's postLower() code which did its own ad-hoc register allocation. And it actually speeds up Om1 translation significantly. This mode of register allocation only allocates for infinite-weight Variables, while respecting live ranges of pre-colored Variables.
