two improvements to RemoveAccessedObjects:
1. if the underlying pointer passed in can be resolved
to any argument or alloca, then we don't need to scan.
Previously we would only avoid the scan if the alloca

2. The dead store processing code is itself completely
dead and didn't handle volatile stores right anyway,

Performance optimization on ImmutableMap/ImmutableSet:
- Use a DenseSet instead of a FoldingSet to cache
canonicalized nodes. This reduces the overhead
of double-hashing.
- Use reference counts in ImutAVLTree to much
more aggressively recover tree nodes that are
no longer usable. We can generate many
transient nodes while using add() and remove()
on ImmutableSet/ImmutableMaps to generate a final
set/map.
For the clang static analyzer (the main client
of these data structures), this results in
a slight speedup (0.5%) when analyzing sqlite3,
but much more importantly results in a 30-60%
reduction in peak memory usage when the analyzer
is analyzing a given function in a file. On
average that's about a ** 44% reduction ** in the
memory footprint of the static analyzer.
