That's right, it isn't -- same as thumb1_return_sequence.ll is incorrect for v4T.

I have a fix for v4T locally, but perhaps we can commit this fix (for v5T, broken since last week) now, and the fix for v4T (broken since July) in a separate, follow-up commit?
The two fixes are more or less independent.
