Changes: Lots of bugs were fixed. Compilation speed was improved. Handling of x86 address mode was completely improved and rewritten. Mul -> Lea,Shift,Add transformation was optimized. 64-bit operations were fixed and improved. More local optimizations were made. New backend peephole optimizations were made. Explicit status flag modeling (only for x86 for now) was added. Load/store optimization and alias analysis were improved. All C benchmarks from Spec CINT2000 work now.
