This is a re-submission of a patch I submitted 15 months ago.
See https://gcc.gnu.org/ml/fortran/2017-09/msg00124.html

At that time one reviewer OK'd the patch for committing,
and one reviewer raised objections to the patch as I
chose to remove dubious extensions to the Fortran standard.
I withdrew that patch with the expection that Someone
would fix the bug.  Well, Someone has not materialized.

The patch has been retested on i586-*-freebsd and x86_64-*-freebsd.

OK to commit as-is?

I say OK to commit.


Here's the text from the above URL.

In short, F2008 now allows boz-literal-constants in IAND, IOR, IEOR,
DSHIFTL, DSHIFTR, and MERGE_BITS.  gfortran currently allows a BOZ
argument, but she was not enforcing restrictions in F2008.  The
attach patch causes gfortran to conform to F2008.

As a side effect, the patch removes a questionable GNU Fortran
extension that allowed arguments to IAND, IOR, and IEOR to have
different kind type parameters.  The behavior of this extension
was not documented.
