bors 1e978a3627 Auto merge of #96946 - WaffleLapkin:ptr_mask, r=scottmcm ... Add pointer masking convenience functions This PR adds the following public API: ```rust impl<T: ?Sized> *const T { fn mask(self, mask: usize) -> *const T; } impl<T: ?Sized> *mut T { fn mask(self, mask: usize) -> *const T; } // mod intrinsics fn mask<T>(ptr: *const T, mask: usize) -> *const T ``` This is equivalent to `ptr.map_addr(|a| a & mask)` but also uses a cool llvm intrinsic.
