Summary: [16 regression] Bootstrap comparison failure with
-march=znver4 -ggdb3 and bootstrap-lto since

bisect.sh
Not sure if something more is going on here. I seem to have stumbled upon this
when looking into another -march=znver4 bootstrap issue w/ 15, but this only
happens on trunk.
Anyway, this one bisects to r16-152-g4f7b3c24112016 with a mismatch in
gimple-match-6.o. It also goes away if I apply -fchecking=1 to stage2.
Will upload the two objects in a minute.
