Zachary Turner d76dc2d31e [lld/pdb] Speed up construction of publics & globals addr map. ...

computeAddrMap function calls std::stable_sort with a comparison
function that computes deserialized symbols every time its called.
In the result deserializeAs<PublicSym32> is called 20-30 times per
symbol. It's much faster to calculate it beforehand and pass a
pointer to it to the comparison function.
