      1. LiveIntervals now implement a 4 slot per instruction model. Load,
         Use, Def and a Store slot. This is required in order to correctly
         represent caller saved register clobbering on function calls,
         register reuse in the same instruction (def resues last use) and
         also spill code added later by the allocator. The previous
         representation (2 slots per instruction) was insufficient and as a
         result was causing subtle bugs.
      
      2. Fixes in spill code generation. This was the major cause of
         failures in the test suite.
      
      3. Linear scan now has core support for folding memory operands. This
         is untested and not enabled (the live interval update function does
         not attempt to fold loads/stores in instructions).
      
      4. Lots of improvements in the debugging output of both live intervals
         and linear scan. Give it a try... it is beautiful :-)
      
      In summary the above fixes all the issues with the recent reserved
      register elimination changes and get the allocator very close to the
      next big step: folding memory operands.
