Brooks Davis 17602eb3ea CHERI: make mem{cpy,move}(9) CHERI compatible ...

- Use intptr_t in place of long as the word type in the core copying
  loop where aligned words a copied.  This preserved the provenance of
  any copied pointers.
- When working with the address of src or dst use ptraddr_t rather than
  uintptr_t.  This avoid ambigious provenance in expressions involving
  multiple addresses.

As a minor tweak, rename the function to memmove since that is the
interface it implements (overlapping src and dst are permitted) and make
memcpy the alias rather than the other way around.
