Improve the kernel target_set.stp and add a stapdyn version
* tapset/linux/target_set.stp: Prefer process.begin/end for better
tracking *process* lifetime. (syscall.exit covers thread exits too!)
* tapset/dyninst/target_set.stp: Implement stapdyn target_set.
* testsuite/systemtap.base/target_set_thread.*: Test that thread exits
don't cause target_set to lose sight of a process.
* main.cxx (run_sdt_benchmark): Save the timing info for verbose runs.
