Initial implementation of a code-completion interface in Clang. In essence, code completion is triggered by a magic "code completion" token produced by the lexer [*], which the parser recognizes at certain points in the grammar. The parser then calls into the Action object with the appropriate CodeCompletionXXX action. Sema implements the CodeCompletionXXX callbacks by performing minimal translation, then forwarding them to a CodeCompletionConsumer subclass, which uses the results of semantic analysis to provide code-completion results. At present, only a single, "printing" code completion consumer is available, for regression testing and debugging. However, the design is meant to permit other code-completion consumers. This initial commit contains two code-completion actions: one for member access, e.g., "x." or "p->", and one for nested-name-specifiers, e.g., "std::". More code-completion actions will follow, along with improved gathering of code-completion results for the various contexts. [*] In the current -code-completion-dump testing/debugging mode, the file is truncated at the completion point and EOF is translated into "code completion". llvm-svn: 82166

Replace the -code-completion-dump option with -code-completion-at=filename:line:column which performs code completion at the specified location by truncating the file at that position and enabling code completion. This approach makes it possible to run multiple tests from a single test file, and gives a more natural command-line interface. llvm-svn: 82571

Eliminate &&s in tests. - 'for i in $(find . -type f); do sed -e 's#\(RUN:.*[^ ]\) *&& *$#\1#g' $i | FileUpdate $i; done', for the curious. llvm-svn: 86430

Tweak the code-completion results ranking and formation, so that members found in base classes have the same ranking as members found in derived classes. However, we will introduce an informative note for members found in base classes, showing (as a nested-name-specifier) the qualification to name the base class, to make it clear which members are from bases. llvm-svn: 82586

Tweak code-completion results by suppressing class template specializations and class template partial specializations (they're never named directly). Also, member access expressions only refer to value declarations (fields, functions, enumerators, etc.) and Objective-C property declarations; filter out everything else. llvm-svn: 91133
