[ThinLTO] Shrink GlobalValueSummary by 8 bytes (#107342)
During the ThinLTO indexing step for one of our large applications, we
create 7.5 million instances of GlobalValueSummary.

Changing:

  std::vector<ValueInfo> RefEdgeList;

to:

  SmallVector<ValueInfo, 0> RefEdgeList;

in GlobalValueSummary reduces the size of each instance by 8 bytes.
The rest of the patch makes the same change to other places so that
the types stay compatible across function boundaries.
