Of course it fails with r14-6114 as that is the source. Doh! I was looking at
pr112827.

tree-optimization/112827 - more SCEV cprop fixes
The insert iteration can be corrupted by foldings of replace_uses_by,
within this particular PHI replacement but also with subsequent ones.
Recompute the insert location before insertion instead.
This fixes an obvserved ICE of gcc.dg/tree-ssa/ssa-sink-16.c.

PR tree-optimization/112848
* tree-scalar-evolution.cc (final_value_replacement_loop):
Compute the insert location for each insert.
