[Bug fortran/30720] runtime: check for empty array slices before allocating a negative amount of memory

Confirming this bug (both of them, actually).

For the missed-optimization, I think there's no reason to keep a library
function _gfortran_internal_free(x) that is equivalent to "if(x) free(x);", we
should generate that code directly.
