Peter Collingbourne 80e2a2f817 Target: Change various section classifiers in TargetLoweringObjectFile to take a GlobalObject.
These functions are about classifying a global which will actually be
emitted, so it does not make sense for them to take a GlobalValue which may
for example be an alias.

Change the Mach-O object writer and the Hexagon, Lanai and MIPS backends to
look through aliases before using TargetLoweringObjectFile interfaces. These
are functional changes but all appear to be bug fixes.
