Ben Konyi d7935c209d [ Profiler ] Avoid building empty CPU profiles when sample streaming is enabled 
Building an empty CPU profile is still costly as function tables are
populated whether or not there's samples in the profile. This change
checks to see if any sample in the list of SampleBlocks was collected
under a UserTag with streaming enabled before building the profile.

TEST=CQ, manual testing
