2014-05-26Add a linear scan register allocator to the optimizing compiler.Nicolas Geoffray
This is a "by-the-book" implementation. It currently only deals with allocating registers, with no hint optimizations. The changes remaining to make it functional are: - Allocate spill slots. - Resolution and placements of Move instructions. - Connect it to the code generator.
