Commit 30979e7d306beac65dadeedb11f3f402c2261bba in impala's branch refs/heads/master from Steve Carlin
[ https://gitbox.apache.org/repos/asf?p=impala.git;h=30979e7d3 ]

IMPALA-13517: Support overloaded || operator

The || operator is used for both "or" and "concat". A new
Impala custom operator is created to handle both of them,
treating the precedence of the operator as if it's an "or".

The "or" is chosen if both parameters are null or boolean, as
taken from logic in CompoundVerticalBarExpr.

At convertlet time (when converting from SqlNode to RelNode),
the real operator is placed into the RexNode.
