bass arch table *32 outputs zero bytes

[PeterLemon]

some cpu architectures allow immediate 32-bit data encoding, right now we can use *08 or *16 with shift rights (>>XXa) to output data correctly in the tables, but it would be nice to have the ability to not need to use shifts for these instructions. also this may confuse people who are new to bass who are making arch tables. (we could document how to get round this if we choose not to fix this specific issue)
