RFR: 8238863: Refactor out static initialization from Dict constructors

[Dean Long]

How about if non-product or debug builds verify the pre-built table 
using the old algorithm?  That should catch the case where someone 
changes shft[] but not xsum[].
I'm not proposing it, but it seems like this table could also be 
generated at build time using awk :-)
