Attached is a patch to drop the U8, U16 and U32 prefixes and
add U and N prefixes.

I havn't added the A prefix because I'm still not clear what
encoding those are supposed to map to. I can understand the
following mappings:

  N => enc_native
  U => enc_utf32

but what is A supposed to map to exactly? or is the assembler
supposed to mangle an A string into an N or U string and then
put it in the bytecode in one of those formats?
