Yuchen Pei e021770667 MDEV-34911 Sargable substr(col, 1, n) = str ... Make Item_func_eq of the following forms sargable by updating the relevant range analysis methods: 1. substr(col, 1, n) = str 2. str = substr(col, 1, n) 3. left(col, n) = str 4. str = left(col, n) where col is a indexed column and str is a const and inexpensive item of length n. We do this by factoring out Item_func_like::get_mm_leaf() and apply it to a string obtained from escaping str and then appending a wildcard "%" to it. The addition of the two Functype enums, LEFT_FUNC and SUBSTR_FUNC, requires changes in the spider group by handler to continue handling LEFT and SUBSTR correctly.
