Do you plan to add support for i386 as well, or is there a reason no such
support is needed (that these registers are call-clobbered and not used
for argument passing / return, so libc needs no special knowledge of
them?)? (Cf. bug 15402 suggesting running the AVX audit tests on i386,
which would make sense if they are valid for x86 even if no associated
changes to the dynamic linker are needed.)

Any new test should have a copyright / license notice immediately
following the first line saying what the function of the file is.
