New crate `xenia-jit` — the PPC->x64 block-JIT runtime substrate, behind
default-OFF XENIA_JIT. Phase 0 ports ZERO opcodes to native: every guest
instruction is emitted as `call jit_interpret_one` (the interpreter), so a
JIT-compiled block is byte-identical to step_block by construction. This
proves the ABI/counters/exit-semantics/mem-helpers/code-cache before any
opcode is hand-written.
- JitEnv{ctx, mem (fat raw ptr), last_result}; compiled block =
extern "C" fn(*mut JitEnv)->u32 (StepResult discriminant, 0=Continue).
Emitted code pins ctx in r15 + env in rbx (callee-saved across calls),
offsets via offset_of!.
- Determinism postlude: cycle_count/timebase +=1 after every retired
instruction; block stops at the same instruction as the interpreter
(non-Continue result, or taken-branch pc discontinuity).
- Per-slot JitCache mirrors BlockCache's (start_pc, page_version) gate;
each CompiledBlock OWNS a copy of its decoded instrs so baked instr
pointers can't dangle after a block-cache eviction.
- xenia-cpu: `pub fn interpret_one` (execute without the cycle bump — the
JIT owns counting).
- Seam: run_superblock main.rs:3154 dispatches to the JIT when enabled;
WorkerCtx gains an Option<JitCache> (Some only when XENIA_JIT set and
RET-CAPTURE debug env unset). observe_per_instruction gate unchanged, so
tooling runs never reach the JIT.
Gate: golden n200m BYTE-IDENTICAL both with and without XENIA_JIT=1.
Throughput -n 200M --gpu-inline: 4.5s interp vs 7.1s all-fallback skeleton
(the per-instruction call overhead Phase 1 removes for hot opcodes).
