Richard Quirk a880469c5a 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.

Edoardo Prezioso 767413adad 1)internal check found a 'findmatch' with simple string argument;
2)Style: uniform 'while (...)' when inside it there's an assignment;
3)Replace '0' with 'NULL' where there's comparison with a pointer.

Richard Quirk d28cf42d4c Fix ticket #3317 (same expression false positives)
Add a check for function calls that have no side effects. That means
known const methods and a list including strcmp, strlen, etc.

If the function is not known to be side effect-free then no style
warning is given.

Add test cases for the duplicate expressions.
