Does anything from TER survive after this patch?
I thought the whole point was that the expansion can see through
the SSA_NAMEs and optimize based on that, by not seeing through
them it doesn't, or if it somewhere still uses get_gimple_for_ssa_name,
if the definition will be already expanded, it might expand stuff multiple
times.
