Mikael Holmen 1587c7e86f [Scalarizer] Treat values from unreachable blocks as undef ... Summary: When scalarizing PHI nodes we might try to examine/rewrite InsertElement nodes in predecessors. If those predecessors are unreachable from entry, then the IR in those blocks could have unexpected properties resulting in infinite loops in Scatterer::operator[]. By simply treating values originating from instructions in unreachable blocks as undef we do not need to analyse them further. This fixes PR41723.
