Detailed Description

A Counter expression builder is used to construct the counter expressions.

It avoids unnecessary duplication and simplifies algebraic expressions.

SubstMap

using llvm::coverage::CounterExpressionBuilder::SubstMap = std::map<Counter, Counter>

K to V map.

K will be Counter in most cases. V may be Counter or Expression.
