branches/5.1: Identify SELECT statements by thd_sql_command() == SQLCOM_SELECT
instead of parsing the query string.  This fixes MySQL Bug #37885 without
us having to implement lexical analysis of SQL comments in yet another place.

thd_is_select(): A new predicate.

row_search_for_mysql(): Use thd_is_select().
