Get the vtable information for a given value.

Parameters

[in]	in_value	The value object to try and extract the VTableInfo from.
[in]	check_type	If true, the compiler type of in_value will be checked to see if it is an instance to, or pointer or reference to a class or struct that has a vtable. If the type doesn't meet the requirements, an error will be returned explaining why the type isn't suitable.
