We do this only when validating since it is a deoptimization. This depends on D1857 to catch such bugs in the RTS (such as #11487). Test Plan: Did a build with ``` BuildFlavour = quick-llvm SRC_HC_OPTS_STAGE1 = -fllvm-fill-undef-with-garbage ``` The build crashed when running ghc-stage2, as expected.
