Applied. The following patch adds the equivalences for the destination

Actually I can't use FOR_EACH_IMM_USE_STMT any longer because
record_equivalence ends up calling has_single_use which doens't
handle the special marker FOR_EACH_IMM_USE_STMT inserts.
hmm, that is unfortunate... and seems almost like a bug to me... Maybe
that should be fixed?
And doesn't that also mean num_imm_uses() has a latent bug if used
during a FOR_EACH_IMM_USE_STMT ?
admittedly neither situation is very common I suspect, but it does seem
like a hidden gotchya waiting to happen.
