Fix 64-bit shift operations.

- Move the declarations of the 64-bit "primops" from PrimOps.h to
  HsBase.h where they more properly belong.

- change the names of the 64-bit shift ops to include the "unchecked"
  prefix

- add checked versions of these primops to GHC.Int and GHC.Word, and
  use them.

- update the FFI declarations in GHC.Int and GHC.Word while I'm there.
