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. Differential Revision: https://reviews.llvm.org/D25917 llvm-svn: 285006
