Revert r282238 "Revert r282235 "[llvm-dwarfdump] - Teach dwarfdump to dump gdb-index section.""
Build bot issues (http://lab.llvm.org:8011/builders/clang-x64-ninja-win7/builds/15856/steps/ninja%20check%201/logs/FAIL%3A%20LLVM%3A%3Adwarfdump-dump-gdbindex.test)
should be fixed in that version. Issue was that MSVS does not support "%zu". Though it works fine on MSCS 2015,
Bot looks running MSVS 2013 that does not like it. MSDN also says that "z" prefix is not supported: https://msdn.microsoft.com/en-us/library/tcxf1dw6.aspx
I had to use PRId64 instead.
Original commit message:
[llvm-dwarfdump] - Teach dwarfdump to dump gdb-index section.
gold linker's --gdb-index option currently is able to create the .gdb_index section that allows GDB to locate and read the .dwo files as it needs them,
this helps reduce the total size of the object files processed by the linker.
More info about that:

Patch teaches dwarfdump tool to dump this section.
