Subject: [PATCH] ProfileSummaryInfo.h - remove unnecessary includes. NFC

Remove a number of includes that aren't necessary (nor are we relying on the remaining includes to provide the declarations), we just needed a llvm::Instruction forward declaration.

This exposed a couple of source files that were implicitly replying on the includes for their use of llvm::SmallSet or std::set, requiring local includes to be added there instead.
