Inside GNATprove, inlining may cause use-clauses to be added in contexts where the entities are already visible. Do not emit warnings about unused use-clauses in these contexts, similar to what is done for instances of generics.
There is no test as only GNATprove is impacted. Tested on x86_64-pc-linux-gnu, committed on trunk 2017-11-08 Yannick Moy <m...@adacore.com> * sem_ch8.adb (Use_One_Type, Update_Use_Clause_Chain): Do not report about unused use-type or use-package clauses inside inlined bodies.
