According to Intel [1]:
According to Dan, __sync_fetch_and_nand intrinsic should be implemented as

comment on gcc manual, only then I remembered many moons ago, I read that
Given various methods for determining byte order on different platforms, the
following can be used in C++ to find the byte order across platforms.
static const uint32_t bytes = 0x03020100ul;

The problem is that -fno-toplevel-reorder is often more restrictive than
-fno-unit-at-a-time used to be. I guess instead of removing the testcase we
should just remove -fno-unit-at-a-time, or add -ftoplevel-reorder.
