getExplicitSectionGlobal - Targets should implement this method to assign a section to globals with an explicit section specfied. The implementation of this method can assume that GV->hasSection() is true.

getKindForGlobal - Classify the specified global variable into a set of target independent categories embodied in SectionKind.
getKindForGlobal - This is a top-level target-independent classifier for a global variable. Given an global variable and information from TM, it classifies the global in a variety of ways that make various target implementations simpler. The target implementation is free to ignore this extra info of course.
