7cdc914b4e MCOL-4809 This patch introduces vectorized scanning/filtering for short CHAR/VARCHAR columns 
Short CHAR/VARCHAR column values contain integer-encoded strings.
    After certain manipulations(orderSwap(strnxfrm(str))) the values
    become integers that preserve original strings order relation
    according to a certain translation rules(collation). Prepared
    values are ready to be SIMD-processed.
