The impl's body block has to end before we make its ImplDecl instruction, and the witness instructions come later, so they don't end up in the body block. Currently they just end up in the enclosing (file, typically, or class) scope block. Add a new InstBlockId to Impl for holding witness instructions, and explicitly insert them into that block. Then include those instructions into the scope of the Impl for naming, and format them into the Impl right after the body block. This is based on #6484
