Redundant, basically two IVs with the same initial value and same step.
IVOPTs can deal with this if the initial values and the step are already
same "enough" - the vectorizer can end up generating redundant huge
expressions for both.
Ah, so yes, this

Redundant or degenerates which should be propagated?
I believe Alan Lawrenc
The following patch adds FRE after vectorization which is needed
for IVOPTs to remove redundant PHI nodes (well, I'm testing a
patch for FRE that will do it already there).
The patch also makes FRE preserve loop-closed SSA form and thus
make it suitable for use in the loop pipeline.
With the pla
