Call continuation logic relies on assumptions about fall-through origin: - the branch is external to the function, - fall-through start is at the beginning of the block, - the block is not an entry point or a landing pad. Leverage trace information to explicitly check whether the origin is a return instruction, and defer to checks above only in case of DSO-external branch source. This covers both regular and BAT cases, addressing call continuation fall-through undercounting in the latter mode.
