Mark fields used by triggers for INSERT-like statement.

mark_fields_used_by_triggers_for_insert_stmt()
thd The current thread
table Table to which insert will happen
duplic Type of duplicate handling for insert which will happen
NOTE
For REPLACE there is no sense in marking particular fields
used by ON DELETE trigger as to execute it properly we have
to retrieve and store values for all table columns anyway.
