Moved ckreads behind the LFS_M_CKREADS flag

Added some code, though we don't _really_ care:

           code          stack
  before: 37872           3048
  after:  38060 (+0.5%)   3056 (+0.3%)

Also interesting to note the difference in testing time, this highlights
_some_ of the performance cost of ckreads:

  with ckreads:    1135.92s
  without ckreads:  821.24s
