In the case of PR53138 this was a preexisting bug in handling -(a < b), made
more explicit by the new phi-opt conversion. Looking at vector-compare-1.c and
pass ordering (phiopt runs before PRE, which hangs while doing PPRE) it is
possible that this is the case too.
I'll make a reduced testcase as soon as possible.
