H A Dmem_helper.c894448ae Sat Nov 12 00:11:22 CST 2022 Richard Henderson <richard.henderson@linaro.org> target/ppc: Use tcg_gen_atomic_cmpxchg_i128 for STQCX

Note that the previous direct reference to reserve_val,

- tcg_gen_ld_i64(t1, cpu_env, (ctx->le_mode
- ? offsetof(CPUPPCState, reserve_val2)
- : offsetof(CPUPPCState, reserve_val)));

was incorrect because all references should have gone through
cpu_reserve_val. Create a cpu_reserve_val2 tcg temp to fix this.
