Masami Hiramatsu d5a00296a6 perf probe: Match linkage name with mangled name 
Match linkage name with mangled name if exists. The linkage_name is used
for storing mangled name of the object.

Thus, this allows 'perf probe' to find appropriate probe point from
mangled symbol as below.

E.g. without this fix:
  ----
  $ perf probe -x /usr/lib64/libstdc++.so.6 \
    -D _ZNKSt15basic_fstreamXXIwSt11char_traitsIwEE7is_openEv
  Probe point '_ZNKSt15basic_fstreamXXIwSt11char_traitsIwEE7is_openEv'
  not found.
    Error: Failed to add events.
  ----

With this fix, perf probe can find the correct one.
  ----
  $ perf probe -x /usr/lib64/libstdc++.so.6 \
    -D _ZNKSt15basic_fstreamXXIwSt11char_traitsIwEE7is_openEv
  p:probe_libstdc/_ZNKSt15basic_fstreamXXIwSt11char_traitsIwEE7is_openEv
  /usr/lib64/libstdc++.so.6.0.22:0x8ca60
  ----

Committer notes:

After the fix, setting it for real (no -D/--definition, that amounts to
a --dry-run):

  # perf probe -x /usr/lib64/libstdc++.so.6 _ZNKSt15basic_fstreamXXIwSt11char_traitsIwEE7is_openEv
  Added new event:
    probe_libstdc:_ZNKSt15basic_fstreamXXIwSt11char_traitsIwEE7is_openEv (on _ZNKSt15basic_fstreamXXIwSt11char_traitsIwEE7is_openEv in /usr/lib64/libstdc++.so.6.0.22)

  You can now use it in all perf tools, such as:

	perf record -e probe_libstdc:_ZNKSt15basic_fstreamXXIwSt11char_traitsIwEE7is_openEv -aR sleep 1

  # perf probe -l probe_libstdc:*
    probe_libstdc:_ZNKSt15basic_fstreamXXIwSt11char_traitsIwEE7is_openEv (on is_open@libstdc++-v3/include/fstream in /usr/lib64/libstdc++.so.6.0.22)
