ART: Reduce the instructions generated by packed switch.

Implement Vladimir Marko's suggestion. The new compare/jump series
reduce the number of instructions from (2*n+1) to (1.5*n+3).

Generate normal compare/jump series when numEntries <= 3.
Generate optimal compare/jump series when numEntries <= threshold.
Generate jump tables otherwise.
