    Supervisor -- trap to a short supervisor mode function

SYNOPSIS
    result = Supervisor(userFunc)
    Rx                   A5

    ULONG Supervisor(void *);

FUNCTION
    Allow a normal user-mode program to execute a short assembly language
    function in the supervisor mode of the processor.  Supervisor() does
    not modify or save registers; the user function has full access to the
    register set.   All rules that apply to interrupt code must be
    followed.  In addition, no system calls are permitted.  The function
    must end with an RTE instruction.

            MOVECtrap:      movec.l VBR,d0  ;$4e7a,$0801
                            rte

INPUTS
    userFunc - A pointer to a short assembly language function ending
               in RTE.  The function has full access to the register set.

RESULTS
    result   - Whatever values the userFunc left in the registers.
