  rts/LoadArchive: Handle string table entries terminated with /
  
  llvm-ar appears to terminate string table entries with `/\n` [1]. This
  matters in the case of thin archives, since the filename is used. In the
  past this worked since `llvm-ar` would produce archives with "small"
  filenames when possible. However, now it appears to always use the
  string table.
