Robert Lougher d469133f95 [Evaluator] Walk initial elements when handling load through bitcast ... When evaluating a store through a bitcast, the evaluator tries to move the bitcast from the pointer onto the stored value. If the cast is invalid, it tries to "introspect" the type to get a valid cast by obtaining a pointer to the initial element (if the type is nested, this may require walking several initial elements). In some situations it is possible to get a bitcast on a load (e.g. with unions, where the bitcast may not be the same type as the store). However, equivalent logic to the store to introspect the type is missing. This patch add this logic. Note, when developing the patch I was unhappy with adding similar logic directly to the load case as it could get out of step. Instead, I have abstracted the "introspection" into a helper function, with the specifics being handled by a passed-in lambda function.
