[llvm-dev] Aligning Long Long Vairables

[Krzysztof Parzyszek via llvm-dev]

Does this happen for individual "long long" variables, or only for 
arrays?  There is something like "long array alignment", and "long array 
size" that could increase the alignment for arrays that are considered 
long (according to these settings).  I don't remember the exact names, 
but it's in the same place in clang.
