Introduce an independent 64-bit extended LLT representation that preserves exact floating-point semantics and supports fixed and scalable vectors. 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.
