untested patch

This is an update of my previous patch, avoids the unaligned mem:DI
in about the same way how a TREE_ADDRESSABLE decl does avoid the invalid code.

Creates good code in the first test case, but a lot worse code (compared to the
previous patch version at least) in the second test case.

So I don't see invalid RTL with this patch.

Thoughts?
