Many thanks to Uros for spotting that I'd forgotten to add constraints
to the new define_insn_and_split *andn<dwi>_doubleword_bmi when moving it
from pre-reload to post-reload. I've pushed this obvious fix after a
make bootstrap on x86_64-pc-linux-gnu. Sorry for the inconvenience to
anyone building the tree with a non-default architecture that enables
BMI.

* config/i386/i386.md (*andn<mode>3_doubleword_bmi): Add constraints
