Sizeof classes/structures during design-time

[vsfeedback]

This issue has been moved from a ticket on Developer Community.

Since intellisense and intellicode are able to levy the compiler to gather so many statistics now, and Visual studio is becoming a better IDE for microcontrollers, I would suggest a way of providing better metrics on classes and structures. As of right now, if I want to know the sizeof a class or struct, I have to either count the data-members, or type out a line inline such as "static constexpr size_t class_size = sizeof(MyClass);" where MyClass is the type I want to determine the size of. This would be very helpful at design time. From my perspective, I see two ways of doing this:

1. Hovering over the typename displays the comment AND the sizeof the type.
2. Right clicking the typename gives the option to calculate the types size (if this operation is more intensive than I suspect).

I am assuming this isn't too big of a step since one can already hover over over a sizeof() expression and see the types size.
