memory profiling with performance analyzer is broken on recent linux kernels

The behavior of "perf probe" has changed. It does not respect the names you give to your trace points anymore. In particular

• It adds a suffix "__return" to any trace points for <function>%return.
• It can create multiple trace point from one "perf probe -x" call, adding _<i> to the name with i being a number.

It seems perf probe is not meant to be used in automated scripts.
