- GenericStringUtf16CharacterStream::start_position_ was unused.
- GenericStringUtf16CharacterStream inherits from BufferedUtf16CharacterStream,
so no need to initialize buffer_cursor_ and buffer_end_ twice (this makes it
clearer which class in the inheritance chain takes care of which variables).

The Isolate* member of ParserBase::FunctionState was only used by
Parser. Removing it makes it clear that there are no isolates in
PreParser. (There's also no Zone, since PreParserTraits::Type::Zone is void.)

- Use the surrounding map (instead of Traits::Impl) for weak callback.
- Provide for a fast reference to a mapped value.
- Restructure Traits to accomondate for the first point above.

[Why?] As discussed, I proceeded to replace Impl with the map.
The problem I encountered with that version is that now the
Traits class depends on itself: The weak-related methods require the
map type in their signature. But the map type includes the Traits class
and hence the Traits class method signatures depend on the specific Traits class. That
makes them practically un-derivable: While you can derive a Traits class
from another one, since the compiler now expects methods with a different
signature. To accommodate, I pulled the dispose traits into the weak traits
class. I also removed the Impl*/MapType* parameter from the Dispose call,
since no implementation seems to need it.

The deopt will not happen in production code, since we check that
lengths of fixed typed arrays are smis before calling
TypedArrayInitialze, but that makes deopt bot happy.

Also added comments to remind us why we were using the hole here in the first
place (it's used for the case where Object.observe, rather than Array.observe,
has been called on Array that's undergoing truncation).

With this fix, we only create the enum cache for own property descriptors (originally we cached all descriptors in the map).  The problem was that the size of all descriptors could be trimmed during GC triggered by allocating the storage for the cache, so we could have ended up with a wrong storage size.

This is really Toon's fix, I have only created a small repro case.

This change makes the reference itself a strong one. We will also need a special handling to make references from MapCache object to Map weak in the heap snapshots. The latter will be addressed separately.
