-//===-- LevelChange.h - Functions for raising/lowering methods ---*- C++ -*--=//
-//
-// This family of functions is useful for changing the 'level' of a method.  
-// This can either be raising (converting direct addressing to use getelementptr
-// for structs and arrays), or lowering (for instruction selection).
