backtrace through uprobes trampoline.
Only works in uretprobes for the moment.
* runtime/stack-x86_64.c (__stp_stack_print): Rewrite trampoline PC
addresses if necessary.
* runtime/stack-i386.c (__stp_stack_print): ditto
* runtime/stack-arm.c (__stp_stack_print): Add extra argument
* runtime/stack-ppc.c (__stp_stack_print): ditto
* runtime/stack-s390.c (__stp_stack_print): ditto
* runtime/stack.c (_stap_stack_print): call __stp_stack_print with
uretprobe_instance.
* testsuite/systemtap.context/uprobe_backtrace.stp: new test
