9769: Improve value flow for ternary operator
...
In some cases, the condition of the ternary operator is assigned a known
value after the two possible results, and in such cases, we would not
take the opportunity to assign a value to the ternary operator (and to
the other parents in the ast).
This patch adds this capability.

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
