Stack maps: Handle special cases using flags.

Keep the BitTable decoder simple (1+NumColumns varints).
Move special case handling up to CodeInfo (empty/dedup).

This speeds up CodeInfo by 5%, and maps startup by 0.05%.
Change in size is negligible (the bits mostly just move).

Test: test.py -b --host --64 --optimizing
