> Add {{hashUTF8String()}} to the hasher classes to allow Spark SQL codegen to generate cleaner code for hashing {{UTF8String}}. No change in behavior otherwise.
> Although with the introduction of SPARK-10399, the code size for hashing {{UTF8String}} is already smaller, it's still good to extract a separate function in the hasher classes so that the generated code can stay clean.
