Replace -flavor {gnu,darwin} with ld64.lld or ld.lld. llvm-svn: 325390

Add support for export_dynamic cmdline option and behaviour. This option matches the behaviour of ld64, that is it prevents globals from being dead stripped in executables and dylibs. Reviewed by Lang Hames Differential Revision: http://reviews.llvm.org/D16026 llvm-svn: 258554

Dead strip DESC bits should only be set on object files. It only makes sense to set on N_NO_DEAD_STRIP on a relocatable object file. Otherwise the bits aren't useful for anything. Matches the ld64 behaviour. llvm-svn: 278419
