Phase 4 - global optimizations

Global optimizations work on the entire method at once. They are more "expensive", requiring larger amounts of compilation time, but can provide a great increase in performance.

The optimizations are:

• Global data flow analyses and optimizations
• Partial redundancy elimination
• Escape analysis
• GC and memory allocation optimizations
• Synchronization optimizations
