  Log Message:
  ovsdb-idlc: Use ALIGNED_CAST to avoid spurious warnings for index rows.

The *_index_init_row() function casts a generic ovsdb_idl_row pointer to
a specific type of row pointer.  This can cause an increase in required
alignment with some kinds of data on some architectures.  GCC complains,

    lib/vswitch-idl.c: In function 'ovsrec_flow_sample_collector_set_index_init_row'
    lib/vswitch-idl.c:9277:12: warning: cast increases required alignment of target

However, rows are always allocated with malloc(), which returns member
suitable for any type, so this is a false positive warning and this commit
suppresses it.
