Function std::intrinsics::volatile_set_memory

pub unsafe extern "rust-intrinsic" fn volatile_set_memory<T>(dst: *mut T,
                                                             val: u8,
                                                             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.memset.p0i8.* 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.
