Deomid Ryabkov 712bd1d773 Try to merge tail with next block when splitting
When splitting a memory block, check if the next block is free.
If it is, then just extend it upwards instead of creating a new block.
This fixes a bug where when shrinking existing allocations would result in irreversible free space fragmentation.

When testing on the host, test all the poisoning configurations.
