[IR] Remove validAlignment and validPointer methods DataLayout as they aren't used.

Browse Source 
I don't think validAlignment has been used since r34358 in 2007. I think validPointer was copied from validAlignment some time later, but it definitely wasn't used in the first commit that contained it.
