Fix num cpu (#1561) 
* add a map of profilers to CPUids

`runtime.NumCPU()` returns the number of CPUs that the process can run
on. This number does not necessarily correlate to CPU ids if the
affinity mask of the process is set.

This change maintains the current behavior as default, but also allows
the user to specify a range of CPUids to use instead.

The CPU id is stored as the value of a map keyed on the profiler
object's address.
