[IRSymtab] Replace linear time lookup with DenseSet (#66376)
There is an inefficiency in the IRSymtab Builder where it does a lookup
of PreservedSymbols when calling addSymbol. This lookup is linear in
time, so it tends to be quite slow. Replacing it with DenseSet gives a
0.1% speedup:

This change is quite similar to https://reviews.llvm.org/D157951.
