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