Attempt to recover gdb bot after r174445. Failure: undefined symbol 'Lline_table_start0'. Root-cause: we use a symbol subtraction to calculate at_stmt_list, but the line table entries are not dumped in the assembly. Fix: use zero instead of a symbol subtraction for Compile Unit 0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174479 91177308-0d34-0410-b5e6-96231b3b80d8

Upgrade tests to the latest debug info format. Mostly this is just changing the named metadata (llvm.dbg.sp, llvm.dbg.gv, llvm.dbg.<func>.lv, etc -> llvm.dbg.cu), adding a few fields to older records (DIVariable: flags/inlined-at, DICompileUnit: sp/gv/types, DISubprogram: local variables list) The tests to update were discovered by a change I'm working on to remove debug info version support - so any tests using old debug info versions I haven't updated probably are bad tests or just not actually designed to test debug info. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176671 91177308-0d34-0410-b5e6-96231b3b80d8

Upgrading debug info test cases to be (more) compatible with the current debug info format. These cases were found by further work to remove support for debug info versioning. Common cleanups (other than changing the version info in the tag field) included adding the last parameter to compile_units (recently added for fission support) and other cases of trailing fields in lexical blocks, compile units, and subprograms. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176834 91177308-0d34-0410-b5e6-96231b3b80d8
