Paul Mackerras 57e7986ed1 perf_counter: Provide a way to enable counters on exec 
This provides a way to mark a counter to be enabled on the next
exec. This is useful for measuring the total activity of a
program without including overhead from the process that
launches it.

This also changes the perf stat command to use this new
facility.
