Lots of constant SSA values we put in the entry block so that CSE can easily combine them. With -N, however, we don't run CSE, so putting values in the entry block only serves to extend their lifetime for no benefit. Fixes #45897. The number of live SSA values per block goes from >5K to 22. Memory use goes from ~3GB to ~400MB.
