Function std::intrinsics::volatile_copy_memory

pub unsafe extern "rust-intrinsic" fn volatile_copy_memory<T>(dst: *mut T,
                                                              src: *const T,
                                                              count: usize)

🔬 This is a nightly-only experimental API.   (core_intrinsics)

intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

Equivalent to the appropriate llvm.memmove.p0i8.0i8.* intrinsic, with a size of count * size_of::<T>() and an alignment of min_align_of::<T>()

The volatile parameter is set to true, so it will not be optimized out.
