CHANGES: Functionally equivalent to Goblint in SV-COMP 2025. * Add 32bit vs 64bit architecture support (goblint/analyzer#54, goblint/analyzer#1574). * Add per-function context gas analysis (goblint/analyzer#1569, goblint/analyzer#1570, goblint/analyzer#1598). * Adapt automatic static loop unrolling (goblint/analyzer#1516, goblint/analyzer#1582, goblint/analyzer#1583, goblint/analyzer#1584, goblint/analyzer#1590, goblint/analyzer#1595, goblint/analyzer#1599). * Adapt automatic configuration tuning (goblint/analyzer#1450, goblint/analyzer#1612, goblint/analyzer#1181, goblint/analyzer#1604). * Simplify non-relational integer invariants in witnesses (goblint/analyzer#1517). * Fix excessive hash collisions (goblint/analyzer#1594, goblint/analyzer#1602). * Clean up various code (goblint/analyzer#1095, goblint/analyzer#1523, goblint/analyzer#1554, goblint/analyzer#1575, goblint/analyzer#1588, goblint/analyzer#1597, goblint/analyzer#1614).

The inspection of not enabling vs enabling
loopUnrollingshowed that unrolling loops in the stub functions do not aid in solving the tasks but only slows down the verification process. Furthermore, in some cases unrolling the loops in stubs too many times causes some regression tests (29/35 nla-sqrtand46/30 autotune-stub) to fail for some (unknown) reason.
