Dehao Chen 1cf0d1a0bd Refine instruction weight annotation algorithm for sample profiler. 
Summary:
This patch refined the instruction weight anootation algorithm:
1. Do not use dbg_value intrinsics for annotation.
2. Annotate cold calls if the call is inlined in profile, but not inlined before preparation. This indicates that the annotation preparation step found no sample for the inlined callsite, thus the call should be very cold.
