move single basic blocks that are neither fallen into nor fall out of into
...
a place more useful. In particular, if we can put them in a place where code
will be able to fall into it, do so. Otherwise, put it in a place it can fall
through into a successor. Otherwise, if preventing a fallthrough, move to the
end of the function, out of the way.
This deletes several hundred unconditional branches from spass.

Minor tweak. Instead of generating:

cmpl $1, %eax
je LBB1_1 #bb
LBB1_4: #entry
cmpl $2, %eax
je LBB1_2 #bb2
jmp LBB1_3 #UnifiedReturnBlock
LBB1_1: #bb
notice that we would miss the fall through and emit this instead:
movl 32(%esp), %eax
cmpl $2, %eax
je LBB1_2 #bb2
LBB1_4: #entry
cmpl $1, %eax
jne LBB1_3 #UnifiedReturnBlock
