Revert "Revert "Debug Info: Using declarations/DW_TAG_imported_declaration of variables, types, and functions."" This reverts commit r181947 (git d2990ce56a16050cac0d7937ec9919ff54c6df62 ) This addresses one of the two issues identified in r181947, ensuring that types imported via using declarations only result in a declaration being emitted for the type, not a definition. The second issue (emitting using declarations that are unused) is hopefully an acceptable increase as the real fix for this would be a bit difficult (probably at best we could record which using directives were involved in lookups - but may not have been the result of the lookup). This also ensures that DW_TAG_imported_declarations (& directives) are not emitted in line-tables-only mode as well as ensuring that typedefs only require/emit declarations (rather than definitions) for referenced types. llvm-svn: 182231

DebugInfo: handle the DI asm printing change to reword '[fwd]' as '[decl]' and add '[def]' for non-decl tag types This is to make test cases looking for definitions more legible by making the definition explicit rather than just the absence of '[fwd]'. This allowed the debug-info-record tests to be rephrased - and in the interests of reducing the number of individual test cases/invocations we have, I merged them into one file, separated them with namespaces (& then moved them to C++ because namespaces are great). If they need to remain 'C' only tests, they can be moved back. (I didn't group them with 'debug-info-class.cpp' because these tests only apply to -fno-limit-debug-info) I removed the pieces of code that would cause these tests to pass under -flimit-debug-info to ensure the tests remain relevant to their fixes should we ever improve -flimit-debug-info to catch that kind of code.
