set the IP in return probes to the returned-to instruction
It's easily available in kretprobes and uretprobes and is consistent
with the rest of the program state.
* translate.cxx (emit_common_header) : add uretprobe_instance to context.
* tapsets.cxx (common_probe_entryfn_prologue): Initialize ri in
context to 0.
(dwarf_derived_probe_group::emit_module_decls): Change IP to return
address in kretprobes.
(uprobe_derived_probe_group::emit_module_decls): enter_uretprobe_probe:
set ri (uretprobe_instance) in context. Change IP to return
address in uretprobes. Don't emit uprobe include and #define
* runtime/runtime.h : Add includes and #define for uprobes.
* runtime/stack.c (_stp_stack_print, _stp_stack_snprint): Add extra
argument for uretprobe_instance.
* tapset/context-unwind.stp (print_backtrace, backtrace): Pass NULL
for uretprobe_instance to _stp_stack_print.
* tapset/ucontext-unwind.stp (print_ubacktrace, ubacktrace): pass
uretprobe_instance to _stp_stack_print
* testsuite/systemtap.context/uprobe_uaddr.exp : new test for uaddr in
function probes
* testsuite/systemtap.context/uprobe_uaddr.stp : new file
