We don't need `NonNull::as_ptr` debuginfo
Stop pessimizing the use of local variables in core by skipping debug info for MIR temporaries in tiny (single-BB) functions. For functions as simple as this -- `Pin::new`, etc -- nobody every actually wants debuginfo for them in the first place. They're more like intrinsics than real functions, and stepping over them is good.
