Fit elements[] to the corresponding types of the struct's fields.
Determine if struct is POD (Plain Old Data).
specifies whether this is a D, C++, Objective-C or anonymous struct/class/interface
Specify whether to mangle the aggregate as a class or a struct This information is used by the MSVC mangler Only valid for class and struct. TODO: Merge with ClassKind ?
Create a new scope from sc. semantic, semantic2 and semantic3 will use this for aggregate members.
Find all instance fields, then push them into fields.
Collect all instance fields, then determine instance size.
Calculate fieldi.overlapped and overlapUnsafe, and check that all of explicit field initializers have unique memory space on instance.
Fill out remainder of elements[] with default initializers for fields[].
Do byte or word alignment as necessary. Align sizes of 0, as we may not know array sizes yet.
Place a member (mem) into an aggregate (agg), which can be a struct, union or class
Flag this aggregate as deprecated
Returns true if there's an extra member which is the 'this' pointer to the enclosing context (enclosing aggregate or function)
Look for constructor declaration.
All struct declarations are an instance of this.
