0N/A// Most optimizations are done in Phases. Creating a phase does any long
0N/A// running analysis required, and caches the analysis in internal data
0N/A// structures. Later the analysis is queried using transform() calls to
0N/A// guide transforming the program. When the Phase is deleted, so is any
0N/A// cached analysis info. This basic Phase class mostly contains timing and
0N/A// memory management code.
