Log:
[analyzer] Mark heap-based symbolic regions in debug dumps.
They are now printed as HeapSymRegion{$x} in order to discriminate between that
and regular SymRegion{$x}, which are two different regions, having different
parent reginos (memory spaces) - HeapSpaceRegion and UnknownSpaceRegion
respectively.
