ARM9TDMI: Fix segfault.
The handler for "arm9tdmi vector_catch ..." did not check if target has already been examined. Without this fix it segfaults when using NULL pointer "arm7_9->eice_cache". Signed-off-by: Antonio Borneo <borneo.antonio@gmail.com> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
