There is a Constant with non-constant operands: blockaddress.

Fix a scalability issue with complex ConstantExprs.2013-04-13T12:53:18ZBenjamin Kramerbenny.kra@googlemail.com2013-04-13T12:53:18Zurn:sha1:8848680ce0ab416cb646d0a03aa6f4f6f25e7623
This is basically the same fix in three different places. We use a set to avoid
walking the whole tree of a big ConstantExprs multiple times.
For example: (select cmp, (add big_expr 1), (add big_expr 2))
We don't want to visit big_expr twice here, it may consist of thousands of
nodes.
The testcase exercises this by creating an insanely large ConstantExprs out of
a loop. It's questionable if the optimizer should ever create those, but this
can be triggered with real C code. Fixes PR15714.
