  -----------
  Remove `__cdecl` from _ReturnAddress (#72919)

As an intrinsic, `_ReturnAddress` does not need it; additionally,
if someone else declares `_ReturnAddress` without `__cdecl` (for
example, `<intrin.h>`)

Additionally, actually add a test for this change. I've tested it
locally with both LLVM and MSVC.
