This builtin, like __builtin_dump_struct, allows for limited
introspection into a struct value. Unlike __builtin_dump_struct, it
makes no assumption that you want to pass the value to printf, and
instead provides a general interface that can be used for any kind of
introspection.

This builtin is supported during constant evaluation. It's also
permitted in C, but not particularly usable there.
