Routine Description:
This function is called to get the 32-bit value of a register from the
specified exception or trap frame.
Arguments:
Register - Supplies the number of the register whose value is to be
returned. Integer registers are specified as 0 - 31 and floating
registers are specified as 32 - 63.
ExceptionFrame - Supplies a pointer to an exception frame.
TrapFrame - Supplies a pointer to a trap frame.
Return Value:
The value of the specified register is returned as the function value.
