/*
 *  _Bitfield_Find_first_bit
 *
 *  DESCRIPTION:
 *
 *  This routine returns the bit_number of the first bit set
 *  in the specified value.  The correspondence between bit_number
 *  and actual bit position is processor dependent.  The search for
 *  the first bit set may run from most to least significant bit
 *  or vice-versa.
 *
 *  NOTE:
 *
 *  This routine is used when the executing thread is removed
 *  from the ready state and, as a result, its performance has a
 *  significant impact on the performance of the executive as a whole.
