[llvm] [CodeExtractor] Add align metadata to extracted pointers (PR #131131)

I had some questions about alignment:
 
 * The StructArgTy is allocated at https://github.com/llvm/llvm-project/blob/e3c80d4496d109397e3c6403df434513fcd50bc6/llvm/lib/Transforms/Utils/CodeExtractor.cpp#L1809. Does this guaranteed to have the alignment returned by `getPointerPrefAlignment`? If so, could add a comment.

 * Shouldn't there be a pass or similar that propagates alignment information from the alloca to the load? Interprocedurally we have the attributor, so what is doing this within a function?
