PR33902: Invalidate line number cache when adding more text to
  existing buffer.

  This led to crashes as the line number cache would report a bogus
  line number for a line of code, and we'd try to find a nonexistent
  column within the line when printing diagnostics.

This fixes an assertion when building the graphics/champlain port.
