This is for PR35460. Currently when LLD adds files to TarWriter it may pass the same file multiple times. For example it happens for clang reproduce file which specifies archive (.a) files more than once in command line. Patch makes TarWriter to ignore files with the same path, so it will add only the first one to archive. Differential revision: https://reviews.llvm.org/D40606 llvm-svn: 319750
