I don't know how to test ilp32 with qemu.  Is there a distribution that uses
this mode, and one tests in system mode?  We don't have user-only support for
ilp32.

I think I have reproduced this with newlib and aarch64-elf.  It could be
solvable by using either unsigned long long, or by using %w constraints with
the two cmp instructions.

Except that I made that change and the failure didn't go away.  I'm having
trouble building a version of gdb that can debug this...
