INT 3C - Borland/Microsoft languages - Floating Point emulation
        This interrupt emulates instructions with a segment override
Note:   the generated code is  CD 3C xy mm ....
        where xy is a modified ESC instruction and mm is the modR/M byte.  The
        xy byte appears to be encoded as
            s s 0 1 1 x x x
        where "ss" specifies the segment override:
                00 -> DS:
                01 -> SS:
                10 -> CS:
                11 -> ES:
