Fortran: reject simplifying TRANSFER for MOLD with storage size 0
gcc/fortran/ChangeLog:
PR fortran/104311
* check.cc (gfc_calculate_transfer_sizes): Checks for case when
storage size of SOURCE is greater than zero while the storage size
of MOLD is zero and MOLD is an array shall not depend on SIZE.
gcc/testsuite/ChangeLog:
PR fortran/104311
* gfortran.dg/transfer_simplify_15.f90: New test.
