Ryan Macnak d7dc524b5f [vm, bytecode] Use call-scoped temporaries for NativeArguments to reduce the frame size of Interpreter::Call. 
This reduces the frame size of Interpreter::Call on Clang x64 from 3544 to 216, and so fixes the stack overflow errors in the kernel service when compiling tests/language_2/deep_nesting_*.  Unlike gcc, Clang would give each local NativeArguments a separate spill slot even though they have disjoint lifetimes.

Aart Bik 622747502e [vm/interpreter] Enforce consistent interpreter/compiler unboxing view 
Rationale:
Both the interpreter and compiler had some logic on when fields
could be unboxed. Rather than duplicating this logic, this CL
uses the same methods to get a more consistent view of unboxing.
Note that this add a slight overhead to the interpreter, but
only a slight. We could avoid this by duplicating the logic
to enforce consistency, but this has the danger of getting
similar issues in the future.

Vyacheslav Egorov a9ce969e53 [vm] Decouple growable_array.h and zone.h from thread.h 
- Introduce a slimmed down version of thread.h, which just depends on the
Zone and StackResource.
- Introduce a layering check that would prevent the coupling in the future.

This is the first step towards decoupling compiler from runtime.

There are multiple reasons to introduce the decoupling but the main
reason currently is to introduce a controlled surface through which
compiler reaches into runtime to catch any places where runtime word size
might influence the compiler and then enable building compiler that
targets 32-bit runtime but is embedded into a 64-bit runtime.
