  Changed paths:
    M llvm/lib/Support/TarWriter.cpp
    M llvm/unittests/Support/TarWriterTest.cpp

  Log Message:
  -----------
  Reland D78945 TarWriter: Only use 137 of the 155 prefix bytes.

With a fix to unittests/Support/TarWriterTest.cpp

This makes lld's --reproduce output more compatible with tar 1.13 and
before.  This is a very old version of tar, but it's the version in
both gnuwin and unxutils, and the cost for supporting them are very
low, so we might as well just do that.

and onward has more details.
