llvm-dwarfdump: Replace -debug-dump=sect option with individual options. As discussed on llvm-dev in http://lists.llvm.org/pipermail/llvm-dev/2017-September/117301.html this changes the command line interface of llvm-dwarfdump to match the one used by the dwarfdump utility shipping on macOS. In addition to being shorter to type this format also has the advantage of allowing more than one section to be specified at the same time. In a nutshell, with this change $ llvm-dwarfdump --debug-dump=info $ llvm-dwarfdump --debug-dump=apple-objc becomes $ dwarfdump --debug-info --apple-objc Differential Revision: https://reviews.llvm.org/D37714 llvm-svn: 312970 2017-09-12 00:59:45 +02:00			`; RUN: llvm-dwarfdump -debug-info %t \| FileCheck %s`

Do a better job at emitting prefrabricated skeleton CUs. This is a better fix than r308708 for the problem introduced in r304020. It restores the skeleton CU testcases modified by that commit to their original form and most importantly ensures that frontend-generated skeleton CUs (such as used to point to Clang modules) come after the regular CUs. This broke for DICompileUnit nodes that don't have any immediate children because they are now constructed lazily instead of the order in which they are listed in !llvm.dbg.cu. After this commit we still don't guarantee that order, but we do guarantee that empty skeletons come last. Shipping versions of LLDB are very sensitive to the ordering of CUs. I'll track a fix for LLDB to be more permissive separately. This fixes a test failure in the LLDB testsuite. rdar://problem/33357252 llvm-svn: 309154 2017-07-26 20:48:32 +02:00			`!0 = distinct !DICompileUnit(language: DW_LANG_C99, file: !1, producer: "LLVM", isOptimized: false, runtimeVersion: 2, splitDebugFilename: "my.dwo", emissionKind: FullDebug, enums: !2, retainedTypes: !2, globals: !2, imports: !2, dwoId: 43981)`
