[LLVMdev] Replacing phi nodes in ScalarEvolution while preserving LCSSA form

[Duncan Sands]

Hi Dan, I whipped up this patch as a more optimal test of whether
replacing the phi node PN by V will break LCSSA form.  I hope it
is more or less correct, but since I know nothing about loops it
could well be completely bogus :)  Can you please comment on it.

Best wishes,

Duncan.
