*	[CodeGen] Implement RV64GC frame lowering	Richard-Qin-X	2026-08-09	1	-2/+10

*	[CodeGen] Model machine debug metadata	Richard-Qin-X	2026-08-02	1	-4/+12
\| \| \| \|	Replace marker-based metadata operands with scoped references and inline DIExpression values. Add structured DILocation chains, instruction debug attachments, stack variable records, and entry values with unified verification, builder support, and deterministic cloning.
*	[CodeGen] Build the core MachineIR object model	Richard-Qin-X	2026-08-01	1	-0/+467
	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.
