[clang] [Clang] Permit noescape on non-pointer types (PR #117344)

I would still like to see a CodeGen test for this to show that it modifies the LLVM-IR.  

I see the attribute is referenced once in our codegen (`CodeGenTypes::arrangeObjCMessageSendSignature`), which looks to modify the IR, so I'd like to see a test that validates this changes with these types.
