The latter first\nmodifies the dst_reg in-place, and later in the delta tracking, the\nsubsequent is_reg_const(src_reg)/reg_const_value(src_reg) reads the\npost-{add,sub} value instead of the original source.\n\nThis is problematic since it sets an incorrect delta, which sync_linked_regs()\nthen propagates to linked registers, thus creating a verifier-vs-runtime\nmismatch.
