Details:

        * Add optimization levels for IA-32 from 0 to 4
(jit_set_optimization_level)
        * Add a new specialized jit_abi_internal
        * Add brand new optimized object code generator (level 1, 2, 3, 4 of
optimization)
        * Various low-level machine dependent optimizations and tricks
        * Aggressive optimization of division by integer constants as
          by Torbjorn Granlund and Peter L. Montgomery in "Division By Invariant
Integers using Multiplication"
          divcnst-pldi94.pdf
        * Add primitive code generators for MMX/Streaming SIMD
Extensions/SSE/SSE2/SSE3 and others
        * Use SIMD SSE/SSE2/SSE3 for floating point values and operations 
(level 1,
2, 3, 4 of optimization\\)
        * Data-flow and control-flow based analysis (level 1, 2, 3, 4 of
optimization)
        * Fast liveness analysis (level 2 of optimization)
        * Dead-code elimination (level 4 of optimization)
        * Full liveness analysis (level 3, 4 of optimization)
        * Linear scan register allocator algorithm (level 2)
        * Bin packing register allocator algorithm (level 3, 4)
        * Tested on DotGNU Portable.NET Common Language Runtime
          / a Microsoft Common Intermediate Language Virtual Machine
