Description:
decimal2bin / bin2decimal is used fairly extensively in code that works on decimal columns. There's some low-hanging fruit in there that we should optimize, for ~10% gain in these routines (possibly a percent or two on some DBT-3 queries).

How to repeat:
N/A

Suggested fix:
N/A

Fixed in 8.0.3.

Minor performance gain. No changelog entry needed.
