message:
Fix Bug#56143 too many foreign keys causes output of show create table to become invalid
Just remove the check whether the file is "too big".
A similar code exists in ha_innobase::update_table_comment() but that
method does not seem to be used.
Also use a CREATE statement with all the FKs instead of ALTERing the
table 550 times because it is faster.
This is a simple optimization issue. All stats are related to only indexed
columns, index size or number of rows in the whole table. UPDATEs that touch
only non-indexed columns cannot affect stats and we can avoid calling the
function row_update_statistics_if_needed() which may result in unnecessary I/O.

TYPE __sync_lock_test_and_set (TYPE *ptr, TYPE value, ...)
it is not documented what happens if the two arguments are of different
type like it was before: the first one was lock_word_t (byte) and the
second one was 1 or 0 (int).

dict_update_statistics_low(): Create bogus statistics for those
indexes that cannot be accessed because of the innodb_force_recovery
setting.
ha_innobase::info(): Calculate statistics for each index, even if
innodb_force_recovery is set. Fill in bogus data for those indexes
that are not accessed because of the innodb_force_recovery setting.
The callers should indicate that the dictionary is locked or not using
the trx->dict_operation_lock_mode == RW_X_LATCH mode. Checking explicitly
for system tables is unnecessary.
