1d289d0146 Fix for PR1831: if all defs of an interval are re-materializable, then it's a preferred spill candiate.

3043dc44cd split the JIT memory management code out from the main JIT logic into its 
own JITMemoryManager interface.  There is no functionality change with 
this patch.

928143423b Commit 44487 broke bootstrap of llvm-gcc-4.2. It is 
not yet clear why, but in the meantime work around the
problem by making less use of readnone/readonly info.

1dc8e83707 - Mark last use of a split interval as kill instead of letting spiller track it. 
This allows an important optimization to be re-enabled.
- If all uses / defs of a split interval can be folded, give the interval a
  low spill weight so it would not be picked in case spilling is needed (avoid
  pushing other intervals in the same BB to be spilled).

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

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).
