Subject: tcg/i386: Adjust assert in tcg_out_addi_ptr
X-Git-Tag: qemu-xen-4.18.0-rc5~226^2~2

tcg/i386: Adjust assert in tcg_out_addi_ptr

We can arrive here on _WIN64 because Int128 is passed by reference.
Change the assert to check that the immediate is in range,
instead of attempting to check the host ABI.
