Targets should depend on all the intrinsics.td files also, otherwise they
...
will compute a locally wrong numbering for the intrinsics. This fixes a
nasty issue where the x86 backend started miscompiling stuff in a 'cvs up'd
build after the altivec intrinsics were added.

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.

cmpl $2, %eax
je LBB1_2 #bb2

notice that we would miss the fall through and emit this instead:

cmpl $2, %eax
je LBB1_2 #bb2
LBB1_4: #entry
cmpl $1, %eax
