Add opaque physical and virtual registers, strongly typed monotonic stable IDs, and atomic MachineFunctionProperties transitions. Export the primitives through RCCBackend::CodeGen, cover their boundary and failure cases, record the frozen invariants, and normalize the architecture document permissions.
