/* For immediate mode, we need the size as specified by the instruction.
   Ordinary operands are therefore encoded as _w, _b, and _l to indicate
   size.
   For now, immediate floating point and immediate values of size > 4 are not
   implemented. _u is used for this.
   The valu_t field is used for the opcode. Most opcodes take one byte.
   The ones that don't take two bytes.

/* BSD 4.3 adb has a different opinion of the bugw and bugl instructions:
   it thinks that an addressing mode byte is required. However, according
   to the VAX-11 Architecture Reference Manual, Revision 6.1, 1982, the
   access type is b, which means that the operand is a branch displacement.
