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. llvm-svn: 176671

Adding DIImportedModules to DIScopes. This is just the basic groundwork for supporting DW_TAG_imported_module but I wanted to commit this before pushing support further into Clang or LLVM so that this rather churny change is isolated from the rest of the work. The major churn here is obviously adding another field (within the common DIScope prefix) to all DIScopes (files, classes, namespaces, lexical scopes, etc). This should be the last big churny change needed for DW_TAG_imported_module/using directive support/PR14606. llvm-svn: 178099

Split out filename & directory from DIFile to start generalizing over DIScopes This is the first step to making all DIScopes have a common metadata prefix (so that things (using directives, for example) that can appear in any scope can be added to that common prefix). DIFile is itself a DIScope so the common prefix of all DIScopes cannot be a DIFile - instead it's the raw filename/directory name pair. llvm-svn: 177239
