Detailed Description

btr_def structs appear on three lists:
     1. A list of all btr_def structures (head is
        ALL_BTR_DEFS, linked by the NEXT field).
     2. A list of branch reg definitions per basic block (head is
        BB_BTR_DEFS[i], linked by the NEXT_THIS_BB field).
     3. A list of all branch reg definitions belonging to the same
        group (head is in a BTR_DEF_GROUP struct, linked by
        NEXT_THIS_GROUP field).
