[PATCH] D17241: [Polly] [Refactor] Move isl_ctx into Scop.

[Tobias Grosser via llvm-commits]

I see. I still would expect that there is an order in which passes are 
freed, but if this is not the case let's go with the shared pointer. I 
do not see how we can allocate all objects under scop's control. That 
seems to be even more complicated.

Best,
Tobias
