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.
Approved by Marko on IRC.
Remove a bogus debug assertion that triggered the bug.
Add assertions precisely where records must not be delete-marked.
And a comment to clarify when the record is allowed to be delete-marked.
Currently we do a full validation of AHI whenever check tables is
called on any table. This patch fixes this by only doing this full
check in debug versions.

The bug is due to a double delete of a BLOB, once via:
rollback -> btr_cur_pessimistic_delete()
and the second time via purge.
The bug is in row_upd_clust_rec_by_insert(). There we relinquish ownership
of the non-updated BLOB columns in btr_cur_mark_extern_inherited_fields()
before building the row entry that will be inserted and whose contents will
be logged in the UNDO log. However, we don't set the BLOB column later to
INHERITED so that a possible rollback will not free the original row's
non-updated BLOB entries. This is because the condition that checks for
that is in :
if (node->upd_ext) {}.
node->upd_ext is non-NULL only if a BLOB column was updated and that column
is part of some key ordering (see row_upd_replace()). This results in the
non-update BLOB columns being deleted during a rollback and subsequently by
purge again.
