Reland r200340 - 'Add line table debug info to COFF files when using a win32 triple' This incorporates a couple of fixes reviewed at http://llvm-reviews.chandlerc.com/D2651 llvm-svn: 200440

Fix PR13202 and a regtest. DwarfDebug class could generate the same (inlined) DIVariable twice: 1) when trying to find abstract debug variable for a concrete inlined instance. 2) when explicitly collecting info for variables that were optimized out. This change makes sure that this duplication won't happen and makes Clang pass "gdb.opt/inline-locals" test from gdb testsuite. Reviewed by Eric Christopher. llvm-svn: 159811

Remove the (apparently) unnecessary debug info metadata indirection. 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. llvm-svn: 174266
