[PATCH] D26256: [InstCombine] Don't set debug location when folding through a phi node

[Robert Lougher via llvm-commits]

No update.  I looked into handling the single line if-then-else case and concluded it was not easy (as Dehao says at this stage you do not know the maximum discriminator value, without redoing the work of AddDiscriminators).  As others want the patch could I add a TODO for now?

Thanks,
Rob.
