[MIPS] Miscellaneous cleanup in prologue analysis code
We usually use backtrace term for dumping a call tree during debug. Therefore this patch renames show_frametrace() into show_backtrace() and show_trace() into show_raw_backtrace(). It also uses the new function print_ip_sym(). Signed-off-by: Franck Bui-Huu <vagabon.xyz@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
