Commit 3574fe89b0cd583265805f7052cac1075c6845cf in impala's branch

IMPALA-13513: Support decode function
The decode operator is similar to the case operator. The tricky part
for supporting the decode is that some of the operands are search
parameters and some are return parameters. The search parameters all
need to be compatible with each other. And the return parameters need
to be compatible with each other as well. Much of the code deals
with casting these parameters to compatible types.
