Thomas Tauber-Marshall 89a3d3c1eb IMPALA-4716: Expr rewrite causes IllegalStateException ...

The DECODE constructor in CaseExpr uses the same decodeExpr object when
building the BinaryPredicates that compare the decodeExpr to each 'when'
of the DECODE. This causes problems when different BinaryPredicates try
to cast the same decodeExpr object to different types during analysis,
in this case leading to a Precondition check failure.

The solution is to clone the decodeExpr in the DECODE constructor in
CaseExpr for each generated BinaryPredicate.

Testing:
- Added a regression test to exprs.test
