Fixes the bootstrap problem reported by Andrew Pinski.  We can't
propagate pointers that don't have the same alias sets as they will
receive different type tags if they are ever dereferenced.
Also, when creating name tags, we need to clear previous name tags if
the pointer hasn't been dereferenced (caught by the verifier).
Bootstrapped and tested x86, x86-64, alpha and ppc. Andrew tells me the patch fixes the regression.

Mainline is currently broken so I won't commit until it's fixed.

On what targets?

Because I just bootstrapped after applying this patch.

Most likely the problem is RTL related and has nothing to do with the
tree level stuff at all.

And since you already broke bootstrap on a secondary target, can you just apply it as you already bootstrapped it?

Thanks,
Andrew Pinski
