Fortran: error recovery from calculation of storage size of a symbol [PR103504]

gcc/fortran/ChangeLog:

	PR fortran/103504
	* interface.cc (get_sym_storage_size): Array bounds and character
	length can only be of integer type.

gcc/testsuite/ChangeLog:

	PR fortran/103504
	* gfortran.dg/pr103504.f90: New test.

(cherry picked from commit 600956c81c784f4a0cc9d10f6e03e01847afd961)
