Fall through to shared suffixes in suffix sharer

IdenticalBlockSuffixSharer inserts the block with the shared suffix
after the first predecessor, which then falls through to it. When the
first predecessor only consists of the shared suffix, it becomes an
empty block and all the other predecessors need a goto to the shared
suffix. Use the largest predecessor instead, so that a predecessor
keeping some instructions falls through to the shared suffix.
