The mcontrol select bit (19) is always zero, meaning our triggers will always match virtual addresses. In this condition, if the user does not specify a size for the trigger, the access size defaults to XLEN.At this moment we're using def_size = 8 regardless of CPU XLEN. Use def_size = 4 in case we're running 32 bits.
