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 2009-09-18 05:32:03 +08:00			`namespace N {`

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 2009-09-23 05:11:38 +08:00			`N::`
Fix FileCheck --check-prefix lines. Various tests had sprung up over the years which had --check-prefix=ABC on the RUN line, but "CHECK-ABC:" later on. This happened to work before, but was strictly incorrect. FileCheck is getting stricter soon though.

Improve the sorting of code-completion results. We now always sort by the "typed" text, first, then take into account nested-name-specifiers, name hiding, etc. This means that the resulting sort is actually alphabetical :) llvm-svn: 93370 2010-01-14 07:24:38 +08:00			`// CHECK-CC1: A`
