[Fortran] Another round of WHERE statement optimizations

Thanks - I went through every single line of the patch itself, checked 
the logic, regtested it and checked out the testcases. The one thing I 
did not do is check out where they were destined to go! However, that 
brings me to a point; ever since I have been involved with gfortran, 
fortran-torture has been more or less deprecated. The entry testcases 
went in there and now the where_xx series. What's the policy, folks and 
what are the issues?

The XFAIL that I think is required argues that this one goes in 
gfortran.dg, no?

Best regards
