SourceLanguage/CLanguageFamily/ExpressionEvaluationJob: - Add TeamTypeInformation parameter to EvaluateExpression() hook. Adjust implementing subclasses and callers accordingly. CLanguageExpressionEvaluator: - Add class InternalVariableID for representing intermediate variables generated while parsing an expression. - When parsing an identifier, if we were passed in a type information object, then first attempt to resolve the name as a type. If not matched, then fall through to attempting to match it to a value node as before. - When parsing an atom, check if it resulted in a type. If it did, and there still remains more of the expression to parse, then parse the result to see what value/variable to try to apply the typecast to. If the result is a primitive, generate an appropriate internal variable + value node child for it, otherwise use the target variable's child. Then, attempt to typecast it as requested. - Simplify _EatToken(). - If the final result of an expression is a type, configure the result object accordingly. As a result of all the above, an expression can now resolve to a type, allowing the evaluator to take over the duties of parsing the desired type for a typecast request in the variables view, and in addition, expressions themselves can now contain typecasts, which opens up quite a few new possibilities.
