Summary0015245: Add support for LTO
DescriptionWhen compiling both with LTO and debugging symbols enabled (at least in clang) one must supply the -object_path_lto option:

-object_path_lto filename
    When performing Link Time Optimization (LTO) and a temporary mach-o object file is needed,
    if this option is used, the temporary file will be stored at the specified path and remain after
    the link is complete. Without the option, the linker picks a path and deletes the object file before
    the linker tool completes, thus tools such as the debugger or dsymutil will not be able
    to access the DWARF debug info in the temporary object file.
