Refactor the same expression check
...
Work out if a function is inconclusive when creating the entry in the
Expressions class instead of when checking the counts at the end. Store
the result in a new bool flag in the ExpressionTokens helper struct.
The pointer to symbol database and ref to list of const functions are
temporarily stored in the Expressions helper class to avoid passing
them in too on every endExpr(tok) call.
Use a const reference to ExpressionTokens in the check loop to avoid
repeating the it->second several times, which clarifies what that code
does.
