bors f9b95f92c8 Auto merge of #86461 - crlf0710:rich_vtable, r=nikomatsakis 
Refactor vtable format for upcoming trait_upcasting feature.

This modifies vtable format:
1. reordering occurrence order of methods coming from different traits
2. include `VPtr`s for supertraits where this vtable cannot be directly reused during trait upcasting.
Also, during codegen, the vtables corresponding to these newly included `VPtr` will be requested and generated.

For the cases where this vtable can directly used, now the super trait vtable has exactly the same content to some prefix of this one.
