[mach-o] create __unwind_info section on x86_64 This is a minimally useful pass to construct the __unwind_info section in a final object from the various __compact_unwind inputs. Currently it doesn't produce any compressed pages, only works for x86_64 and will fail if any function ends up without __compact_unwind. rdar://problem/18208653 llvm-svn: 218703

[mach-o] make __unwind_info defer to __eh_frame when necessary. Not all situations are representable in the compressed __unwind_info format, and when this happens the entry needs to point to the more general __eh_frame description. Just x86_64 implementation for now. rdar://problem/18208653 llvm-svn: 219836

[mach-o] remove __compact_unwind atoms once __unwind_info has been generated The job of the CompactUnwind pass is to turn __compact_unwind data (and __eh_frame) into the compressed final form in __unwind_info. After it's done, the original atoms are no longer relevant and should be deleted (they cause problems during actual execution, quite apart from the fact that they're not needed). llvm-svn: 221301
