The main lists of debug info metadata attached to the compile_unit had an extra layer of metadata nodes they went through for no apparent reason. This patch removes that (& still passes just as much of the GDB 7.5 test suite). If anyone can show evidence as to why these extra metadata nodes are there I'm open to reverting this patch & documenting why they're there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174266 91177308-0d34-0410-b5e6-96231b3b80d8
