Applied to GCC 6 branch.  Thanks!
Please remember adding the PR number to the changelog entries to trigger bugzilla adding a comment
to the PR.

As discussed offlist the range check for the position operand could be moved to a predicate.  This
will be part of the GCC head patch.

I've just noticed that I had such checks already for the insv patterns and have added one to the
expander as well later. So for zero_extract as target operand this appeared to be a problem even
before GCC 6.

Bye,
