vect file for r16-1001-g0291f53f8d2343
Since commit r16-1001-g0291f53f8d2343 (also tested on today's
r16-3610-g1179ac1fabf346, with the same result), this test fails on
aarch64-linux-gnu:

I'll attach the .s and .vect files from the commit which introduced the
regression and from its parent.
Would it help to also attach the .s and .vect files from current trunk? I
didn't because I assume it may have more unrelated changes, but I also have
them.
