This reduces the memory consumption of SourcePositionTable by ca. 2/3. Over Octane, this reduces the source position table memory consumption from ~370kB to ~115kB, which makes it ca. 10% of the total bytecode size (~1.1MB) ---------------- Reland CL in order to relive the glory days, and also fix memory leak w/ ENABLE_SLOW_CHECKS. SourcePositionTableBuilder used to have a no destructor since everything was zone allocated. But if ENABLE_SLOW_CHECKS, it has a heap allocated member and thus needs a proper constructor. ASAN thankfully notices this, and V8 no longer builds since this is called during mksnapshot.
