[CodeComplete] Fix completion at the end of keywords Summary: Make completion behave consistently no matter if it is run at the start, in the middle or at the end of an identifier that happens to be a keyword or a macro name. Since completion is often ran on incomplete identifiers, they may turn into keywords by accident. For example, we should produce same results for all of these completion points: // ^ is completion point. ^class cla^ss class^ Previously clang produced different results for the last case (as if the completion point was after a space: `class ^`). This change also updates some offsets in tests that (unintentionally?) relied on the old behavior.
