[PATCH] D32877: Restrict call metadata based hotness detection to Sample PGO mode

I feel the underlying problem here is the use of VP metadata to get counts in sample PGO mode.  Dehao, even when VP metadata is available, can we add branch_weights to the call? Then, only sample PGO will annotate branch weights to calls and that won't affect instrumented PGO.
