* mn10300-opc.c (mn10300_operands): Hijack "bits" field
in MN10300_OPERAND_SPLIT operands for how many bits
appear in the basic insn word. Add IMM32_HIGH24,
IMM32_HIGH24_LOWSHIFT8, IMM8E_SHIFT8.
(mn10300_opcodes): Use new operands as needed.
Support for everything in the basic instruction manual (yippie!)
