Arnaldo Carvalho de Melo d7a07b2932 perf trace: Resolve prctl's 'option' arg strings to numbers 
# perf trace -e syscalls:sys_enter_prctl --filter="option==SET_NAME"
     0.000 Socket Thread/3860 syscalls:sys_enter_prctl(option: SET_NAME, arg2: 0x7fc50b9733e8)
     0.053 SSL Cert #78/3860 syscalls:sys_enter_prctl(option: SET_NAME, arg2: 0x7fc50b9733e8)
^C  #

If one uses '-v' with 'perf trace', we can see the filter it puts in
place:

  New filter for syscalls:sys_enter_prctl: (option==0xf) && (common_pid != 3859 && common_pid != 2757)

We still need to allow using plain '-e prctl' and have this turn into
creating a 'syscalls:sys_enter_prctl' event so that the filter can be
applied only to it as right now '-e prctl' ends up using the
'raw_syscalls:sys_enter/sys_exit'.

The end goal is to have something like:

  # perf trace -e prctl/option==SET_NAME/

And have that use tracepoint filters or eBPF ones.
