Comment(by vivian):

 I have begun by adding
 {{{
 Int32Packed4#
 Int64Packed2#
 FloatPacked2#
 DoublePacked4#
 }}}
 as primitive datatypes.  This includes adding the primitive mathematical
 and logical operations that Cmm uses (which are the C primitives).

 I am currently '''not''' providing non-hash versions of these datatypes
 (e.g. `Int32Packed4`).

 Also added are primitive `Array#`s for these packed types.
