Add the majority of the vector machien value types we expect to support,

16 types.
Just in case anyone cares, the relevant vector types for alpha are:
v8i8, v4i16, and maybe v2i32 (only one unpack operation produces this
and one pack operations consumes it). Of course all the operations that
exist are (s|u)(min|max), packing, unpacking, and comparison. Not that
I am too worried about support.
Ok, sounds good. We figured that the list could be expanded on demand. :)
MMX also has several other supported types that aren't on the list, so we
would add those if we ever decided to add support.
