Add DCHECKs to ArenaVector and ScopedArenaVector.
Implement dchecked_vector<> template that DCHECK()s element
access and insert()/emplace()/erase() positions. Change the
ArenaVector<> and ScopedArenaVector<> aliases to use the new
template instead of std::vector<>. Remove DCHECK()s that
have now become unnecessary from the Optimizing compiler.

Optimizing: Tag more arena allocations.
Replace GrowableArray with ArenaVector and tag arena
allocations with new allocation types.
As part of this, make the register allocator a bit more
efficient, doing bulk insert/erase. Some loops are now
O(n) instead of O(n^2).

Optimizing: Tag arena allocations in HGraph.
Replace GrowableArray with ArenaVector in HGraph and related
classes HEnvironment, HLoopInformation, HInvoke and HPhi,
and tag allocations with new arena allocation types.

Add a GVN dependency 'GC' for garbage collection.
This will be used by incoming architecture specific optimizations. The
dependencies must be conservative. When an HInstruction is created we
may not be sure whether it can trigger GC. In that case the
'ChangesGC' dependency must be set. We control at code-generation time
that HInstructions that can call have the 'ChangesGC' dependency
set.

Improved side effect analysis (field/array write/read).
Rationale:
Types (int, float etc.) and access type (field vs. array)
can be used to disambiguate write/read side-effects analysis.
This directly improves e.g. dead code elimination and licm.

Move code around and address growable_array comment.
- Move SideEffectsAnalysis to its own file.
- Move most of gvn.h to gvn.cc.
- Don't call Resize in GrowableArray constructor, but just set num_used
directly.
