Hi Ravi,

I can rework the patch to use the is_supported() member function. The
down side is that the test does not show up in the list of executed tests anymore,
unless some debug output is enabled:

[root@s8360046 perf]# ./perf test -F 22
[root@s8360046 perf]# ./perf test -Fv 22
22: Watchpoint : Disabled
[root@s8360046 perf]#

I leave it to Arnaldo to decide...
