The `frame variable` command supports an implicit `this`/`self`, allowing a
user to run `v some_field` instead of `v this->some_field`. However, some
languages have non-pointer `this`/`self` types (for example, Swift).
With this change, support for non-pointer implicit `this`/`self` is supported.
This is done by consulting the type of the instance variable. If the type is
known to be non-pointer, then the dot operator `.` is used instead of the arrow
operator `->`.
The C language of families each have a pointer instance type, which makes
testing of this difficult. Tests for this feature will be done in the Swift
downstream fork, as Swift's `self` is a non-pointer (reference) type.
