DWARF v5 specifies that the root file (also given in the DW_AT_name attribute of the compilation unit DIE) should be emitted explicitly to the line table's list of files. This makes the line table more independent of the .debug_info section. We emit the new syntax only for DWARF v5 and later. Fixes the bug found by asan. Also XFAIL the new test for Darwin, which is stuck on DWARF v2, and fix up other tests so they stop failing on Windows. Last but not least, don't break "clang -g" of an assembler file that has .file directives in it. Differential Revision: https://reviews.llvm.org/D44054 llvm-svn: 328805
