Kristina Bessonova e15019e197 [llvm-dwarfdump][Statistics] Unify coverage statistic computation ... Summary: The patch removes OffsetToFirstDefinition in the 'scope bytes total' statistic computation. Thus it unifies the way the scope and the coverage buckets are computed. The rationals behind that are the following: 1. OffsetToFirstDefinition was used to calculate the variable's life range. However, there is no simple way to do it accurately, so the scope calculated this way might be misleading. See D69027 for more details on the subject. 2. Both 'scope bytes total' and coverage buckets seem to be intended to represent the same data in different ways. Otherwise, the statistics might be controversial and confusing. Note that the approach gives up a thorough evaluation of debug information completeness (i.e. coverage buckets by themselves doesn't tell how good the debug information is). Only changes in coverage over time make a 'physical' sense.
