Extended Description

While testing MachineLICM I found a regression in
test/CodeGen/X86/pre-split2.ll. By making a minor edit
to this testcase, I can reproduce the failure without running
MachineLICM. Attached is the modified testcase.

My currently uncommitted patches to enable phi join creation and interval reconstruction fix this. I'll close this once they go into the tree.

This was fixed a while back.
