intel: avoid unnecessary front buffer flushing/updating
Before, if we just called glXMakeCurrent() and didn't render anything we'd still trigger a flushFrontBuffer() call. Now only set the intel->front_buffer_dirty field at state validation time just before we draw something. NOTE: additional calls to intel_check_front_buffer_rendering() might be needed if I missed some rendering paths.
