[llvm-commits] Patch to delete PHI nodes with multiple uses

[Andrew Clinton]

Yes, I thought that "areAllUsesEqualAndHasAtLeastOneUse" was too
verbose.  Actually I was wondering why the instruction even needs
multiple use entries in this case - why not collapse it to a single
entry?  That would have made this change unnecessary.
