For this failure mode to be possible, the target has to provide
TImode, but *not* TFmode. I'm not sure which targets other than
s390x do that. And even so, it is a reload issue, so it tends
to trigger only very under particular circumstances. The specific
test case we have would not trigger that failure mode even on
targets where it exists.
