Fix handling of maximum value for MAX_ROWS on 64-bit platforms. (Bug #14155)

mysql-test/r/create.result:
  Add new results
mysql-test/t/create.test:
  Add regression test
sql/table.cc:
  To cap a value at 2^32-1 on a 64-bit platform, use UINT_MAX32, not
  ~(ulong)0, since a ulong may be 64-bit itself.
