    rts: Specialize hashing at call site rather than in struct
    
    Separate word and string hash tables on the type level, and do not
    store the hashing function.
    Thus when a different hash function is desire it is provided upon
    accessing the table. This is worst case the same as
    before the change, and in the majority of cases is better. Also mark
    the functions for aggressive inlining to improve performance.
