This is a regression introduced by r228599.
I'm attaching the output of -save-temps for all three files, the good assembly
from r228598 (last good commit) and the bad assembly from r228599.

I can't generate a better or simpler testcase, sorry.

This should be the same as PR67947 which has a testcase.
