Andrew Lenharth 3196422df0 Handle one offset with growth case seen in povray. Namely, if we have an offset, 
and the offset lands at a field boundary in the old type, construct a new type,
copying the fields masked by the offset from the old type, and unify with that.

Chris Lattner 990ed1d201 Change the ActualCallees callgraph from hash_multimap<Instruction,Function> 
to std::set<std::pair<Inst,Func>> to avoid duplicate entries.

eqgraph passes from 1.5s to .16s on the same.

Chris Lattner 2ba37389c9 Cache mapping information for a call site after computing it for a mod/ref 
query.  If the next mod/ref query happens to be for the same call site
(which is extremely likely), use the cache instead of recomputing the
callee/caller mapping.  This makes -aa-eval ***MUCH*** faster with
ds-aa
