Subject: [CodeGen] Build the core MachineIR object model

Add arena-owned, address-stable MachineFunction, MachineBasicBlock, and MachineInstr nodes with intrusive layout and instruction lists. Model every required MachineOperand category, reciprocal ties, source state, and immutable per-instruction memory references.

Implement physical and virtual register def-use chains whose back-links survive operand vector moves, plus vreg properties, tombstones, live-ins, reserved registers, and atomic CFG updates. Exercise ownership, reallocation, unlink/relink, cross-function rejection, and sanitizer paths.
