914befbc8a Implement framework for scalarizing node results. This is sufficient 
to codegen this:

define float @test_extract_elt(<1 x float> * %P) {
	%p = load <1 x float>* %P
	%R = extractelement <1 x float> %p, i32 0
	ret float %R
}

90d6c0aea2 Track dependencies when creating symlinks to LLVM libraries next 
to the ocaml bindings. This is required on Windows where 'ln -sf'
actually creates a copy. Thanks to Alain Frisch for noticing this.

1e2e4972ff Rather than having special rules like "intrinsics cannot 
throw exceptions", just mark intrinsics with the nounwind
attribute.  Likewise, mark intrinsics as readnone/readonly
and get rid of special aliasing logic (which didn't use
anything more than this anyway).

14f11d6836 Integrate the readonly/readnone logic more deeply 
into alias analysis.  This meant updating the API
which now has versions of the getModRefBehavior,
doesNotAccessMemory and onlyReadsMemory methods
which take a callsite parameter.  These should be
used unless the callsite is not known, since in
general they can do a better job than the versions
that take a function.  Also, users should no longer
call the version of getModRefBehavior that takes
both a function and a callsite.  To reduce the
chance of misuse it is now protected.

cf224f3721 Fix a major performance issue with splitting. If there is a def (not def/use) 
in the middle of a split basic block, create a new live interval starting at
the def. This avoid artifically extending the live interval over a number of
cycles where it is dead. e.g.

bb1:
       = vr1204   (use / kill) <= new interval starts and ends here.
...
...
vr1204 =          (new def)   <= start a new interval here.
       = vr1204   (use)
