Fix for PR960. Improves bugpoint so that it removes global variable
...
initializers as well. This is only a first pass. It can be slow because
it clones the module for each pass. An obvious improvement is not to do that.

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.
