inspection of namespaces in the expression parser. ClangExpressionDeclMap hitherto reported that namespaces had been completely imported, even though the namespaces are returned empty. To deal with this situation, ClangASTSource was recently extended with an API to complete incomplete type definitions, and, for greater efficiency, to complete these definitions partially, returning only those objects that have a given name. This commit supports these APIs on LLDB's side, and uses it to provide information on types resident in namespaces. Namespaces are now imported as they were -- that is to say, empty -- but with minimal import mode on. This means that Clang will come back and request their contents by name as needed. We now respond with information on the contained types; this will be followed soon by information on functions and variables. llvm-svn: 133852
