In tcg_out_qemu_ldst_i128, we need a non-zero index register,
which we then use as a base register in several address modes.
Since we always have TCG_REG_TMP2 available, use that.
In tcg_out_qemu_st, in the fallback when STDBRX is not available,
avoid clobbering TCG_REG_TMP1, which might be h.base, which is
still in use. Use TCG_REG_TMP2 instead. Since the final use of
h.index is that ADDI, there is no conflict with the above.
