Fix non-short-circuited tests in ILAxL{C,R}.
Fortran doesn't short-circuit logical operators, so the check that the leading
dimension /= 0 may not prevent indexing into a 0-length array.
Reported by "hes selex" in
http://groups.google.com/group/comp.lang.fortran/browse_thread/thread/635192e11beadb93
and forwarded to the LAPACK maintainers by Tobias Burnus <burnus@net-b.de>.
Chalk up more bugs found by gfortran's diagnostics!
