com.c (ffecom_overlap_): Set source_offset to bitsize_zero_node.
* com.c (ffecom_overlap_): Set source_offset to
bitsize_zero_node.
(ffecom_tree_canonize_ptr_): Use size_binop. Convert to
bitsizetype before multiplying by TYPE_SIZE.
(ffecom_tree_canonize_ref_) [case ARRAY_REF]: Break up offset
calculation. Convert to bitsizetype before multiplying by
TYPE_SIZE.
