Fix for bug #18153 "ALTER/OPTIMIZE/REPAIR on transactional tables corrupt

Browse Source 
triggers".

Applying ALTER/OPTIMIZE/REPAIR TABLE statements to transactional table or to
table of any type on Windows caused disappearance of its triggers.
Bug was introduced in 5.0.19 by my fix for bug #13525 "Rename table does not
keep info of triggers" (see comment for sql_table.cc for more info).
