The miscompiled function seems to be evaluate_stmt or possibly the
functions it is inlined to because the transformation happens in early
SRA.
Nevertheless, when we revert to the old behavior (enum type scalar
replacements) when creating a replacement for val.lattice_val in this
function the bootstrap finishes.
