[Bug fortran/36153] New: ICE on size with kind parameter

["J dot Hogg at rl dot ac dot uk" <gcc-bugzilla@gcc.gnu.org>]

Use of an optional kind parameter on a call to the intrinsic size was added in
Fortran 2003, and is essential to avoid overflow when dealing with arrays
bigger than huge(0). The following example provides test code and demonstrates
this.
gfortran should warn that this is non-standard fortran 90/95 and fail
gracefully, and/or work as per the F2003 spec.

Thanks,
Jonathan.
