[pprof] Produce global profile unless thread-local profile requested

Browse Source 
Currently pprof will print output for all threads if a single thread is not
specified, but this doesn't play well with many output formats (e.g., any of
the dot-based formats).  Instead, default to printing just the overall profile
when no specific thread is requested.

This resolves #157.
