Prepare for LLVM 15

[fabianbs96]

Story

Prepare PhASAR for LLVM 15 and beyond:

• Get rid of llvm::Type::getPointerElementType() and llvm::PointerType::getElementType()
• How should we deal with IfdsFieldSensTaintAnalysis? It heavily relies on non-opaque pointers
  • Decided to drop it

Edit: Now that LLVM 16 is already released we may skip LLVM 15 and go to 16 directly.
