Hi!

This patch fixes PR rtl-optimization/28489.

The first problem is that we create new basic block for unreachable 
instructions in the wrong place (in the middle of current block) - 
sadly, that's my typo.

The second problem is that we should skip empty blocks during EBB 
scheduling so that there will be no need to move jumps between blocks 
when that is not needed.

::ADDPATCH scheduler:

Thanks,
Maxim
