             The instruction range is specified after the FROM
             option on the TRACE command. 64-bit addresses will
             be saved.
             When we have determined that the trace command is
             valid, these addresses are saved in TRPIRNG.

             The target range is specified after the INTO
             option on the TRACE command. 64-bit addresses will
             be saved.
             When we have determined that the trace command is
             valid, these addresses are saved in TRPBRNG for
             BRANCH traps or TRPSRNG for STORE traps.

             TRWGMASK and TRWMASK must be defined with the same
             format as TRPGGPRM and TRPARM.  There is code that
             is dependent on these fields being defined so that
             they can overlay each other.
