Hello please review this small fix for AIX (needed  with  the new xlc16) .

Currently  we miss function names in the hs_err file  :

0x0000000115098660 - 0x090000000f629a4c libjvm.so::<nameless function>+0x6c (C++ saves_lr stores_bc gpr_saved:4 )
0x00000001150986f0 - 0x09000000113594bc libjvm.so::<nameless function>+0x95c (C++ saves_lr stores_bc gpr_saved:18 )

The output contains "nameless function"  instead of the  (member) function names .
Looks like this unwanted behavior  was introduced when switching to the  xlc16  compiler.

With xlc16, it looks like we have to  configure  the traceback table generation to get the output we need.

The -qtbtable=full   setting can be used for this _


Bug / webrev :



Thanks, Matthias
