/*
 * DisassemblePowerPC(op, vpc, mnem, oprs, simplify):
 *
 * Disassembles one PowerPC 603e instruction. 
 *
 * A non-zero return code indicates that the instruction could not be
 * recognized or that the operands to an instruction were invalid. To
 * determine which case occured, check if mnem[0] == '\0'. If it does not,
 * then the latter case happened.
 *
 * Arguments:
 *      op         Instruction word to disassemble.
 *      vpc        Current instruction address.
 *      mnem       Buffer to write instruction mnemonic to. If no
 *                 instruction was decoded, mnem[0] and oprs[0] will be set
 *                 to '\0'.
 *      oprs       Buffer to write any operands to.
 *      simplify   If non-zero, simplified forms of instructions will be
 *                 printed in certain cases.
 *
 * Returns:
 *      OKAY if successful, FAIL if the instruction was unrecognized or had an
 *      invalid form (see note above in function description.)
