As for proposal to revert the aliasing fixes on the 4.2, IMHO aliasing

All bugs we are talking about can be worked around by using
-fno-strict-aliasing.
It is too conservative and I think seriously descreases performance
too. Although it would be interesting to see what degradation we would
have with usage of the option. May be it is not so bad. In that case,
your proposal would be reasonable because it is much less work.
