perf probe: Support argument name
Set given names to event arguments. The syntax is same as kprobe-tracer,
you can add 'NAME=' right before each argument.
e.g.
./perf probe vfs_read foo=file
then, 'foo' is set to the argument name as below.
./perf probe -l
probe:vfs_read (on vfs_read@linux-2.6-tip/fs/read_write.c with foo)
