The second part of support for generating dwarf for assembly source files. This generates the dwarf Compile Unit DIE and a dwarf subprogram DIE for each non-temporary label. The next part will be to get the clang driver to enable this when assembling a .s file. rdar://9275556 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146262 91177308-0d34-0410-b5e6-96231b3b80d8
