- MIParser: If the successor list is not specified successors will be added based on basic block operands in the block and possible fallthrough. - MIRPrinter: Adds a new `simplify-mir` option, with that option set: Skip printing of block successor lists in cases where the parser is guaranteed to reconstruct it. This means we still print the list if some successor cannot be determined (happens for example for jump tables), if the successor order changes or branch probabilities being unequal.
