Nikolai Kosjar 05c1efd8ef Clang: Fix dot-arrow-correction for not-yet-parsed unsaved content ...

The issue was re-producible with e.g.:

    void g()
    {
        // Type 'foo.' as fast as possible in the next line

    }

This led to "foo->" with completion results as if there was no "foo." at
all in that line.

We relied on a correct position for
translationUnit.sourceLocationAtWithoutReparsing(), but the just typed
characters were not yet reparsed. And we do not want to reparse at that
point since takes too long. We already determine the utf8 position for
the dot character, so simply use that instead.

This completes commit 17c1325cc4.
