intrinsics: Add copy_nonoverlapping<T>
This intrinsic is similar to C's memcpy (or in our case, GCC's
__builtin_memcpy) with the order of arguments swapped and knowledge
about the type of the operands. So we can desugar the following calls:
`copy_nonoverlapping::<T>(src, dst, count)`
can be converted to
`__builtin_memcpy(dst, src, count * size_of::<T>())`
Finally, unlike most intrinsics, copy_nonoverlapping must be marked as impure
