[PR fortran/89516, patch] - ICE in gfc_calculate_transfer_sizes at gcc/fortran/check.c:5506

Subject: [PR fortran/89516, patch] - ICE in gfc_calculate_transfer_sizes at gcc/fortran/check.c:5506

Adding -Wsurprising as option to gfortran exercised a code path
that I hadn't seen when working on simplifications for the TRANSFER
intrinsic.  While regtesting, I realized that one of the checks was
too strict when the MOLD argument was scalar and of size 0 and should
only apply to array arguments.  I adjusted the corresponding testcase.

Regtested on x86_64-pc-linux-gnu.

OK for trunk?
