Add register value tracking (jit_regs) to all JIT backends (x86-64, aarch64, armv6m, riscv32). This enables optimization of redundant loads when a register already contains the needed value. Factor out shared value_to_contents and vm_dest_to_contents helpers into jit_regs module. Add regs_to_mask/2 to replace per-backend duplicated regs_to_mask/1 functions. Add invalidate_volatile/2 for correct cache management after function calls. Signed-off-by: Paul Guyot <pguyot@kallisys.net>
