PKEuS dc701276de Optimizations to ValueFlow and ForwardAnalyzer: 
- Remove errorPath of a value on assignment (this fixes enormous memory consumption for code with many subsequent assignments)
- De-virtualized a simple get function that was virtual for no reason
- Cloned function isAliasOf() for single values to avoid instantiating unnecessary std::list objects (
- Replaced a couple of trivial Token::Match/simpleMatch expressions by direct comparison
- Treat enumerators as literal values

This reverts commit b25709a492.

The real problem was wrong AST for valid code, I want to fix that instead.
