So 3.3 expanded the initializer into sets of the individual components, but
with ANDs and ORs and a single MEM store, instead of MEM stores to the
individual components.
It seems to me that this is not something you'd want to fix with a tree
optimizer. Maybe some local (i.e. per basic block) RTL pass:
1. Collect all stores
2. Find related stores
3. Combine related stores where possible and cheaper
I don't think this is not fixable for GCC 4.3.
