r201608 made llvm corretly handle private globals with MachO. r201622 fixed a bug in it and r201624 and r201625 were changes for using private linkage, assuming that llvm would do the right thing. They all got reverted because r201608 introduced a crash in LTO. This patch includes a fix for that. The issue was that TargetLoweringObjectFile now has to be initialized before we can mangle names of private globals. This is trivially true during the normal codegen pipeline (the asm printer does it), but LTO has to do it manually. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201700 91177308-0d34-0410-b5e6-96231b3b80d8
