Optimize replace_chunk() for replacements at the end of the block
If the new block replaces the tail of the original block,
replace_chunk() currently splits the block, moves some pointers to
the newly allocated head block, moves the remaining pointers to the
new block, shrinks the original block to zero and kills it.
In this case, it is better to shrink the original block and the new
block after it.
