Reduce the amount of full code generated to fill out array literals.
...
This is achieved by tuning the calling convention of StoreArrayLiteralStub:
* The map of the array literal can be loaded in the stub from the
array literal itself, there is no need to pass it at all.
* The array literal is already on the stack, so there is no need to
pass it again via a register.
* The literal index is unchanged while filling the literal, so we can
push it on the stack once and avoid passing it every time. Note that
we need to mirror this change in the stack layout in crankshaft, too.

Turn off allocation site info for crankshafted array constructor calls.
...
Once we crankshaft a method, we should turn off allocation site info for
constructed arrays. Additionally, the semantics for doing this were
awkward because the constructed array code stubs get an
AllocationSiteMode as a minor key, but it's used as a permission to
determine the final mode locally based on ElementsKind. I refactored
this to a simpler boolean for override or local control.

Collect type feedback in separate pass and store it in AST
...
Notes:
- For now, just adds the missing type info fields to the AST nodes directly.
I'd like to factor that out more nicely in a follow-up CL.
- All type feedback now is uniformly collected through AST nodes'
RecordTypeFeedback functions. At some point, this logic should be moved
out of ast.cc.
- The typing pass currently simulates the exact same conditions under
which feedback was collected in Hydrogen before. That also should be
made more generic in the future.
- Type information itself is unchanged. Making it more regular is
yet more future work.
Some additional cleanups:
- Lifted out nested class ObjectLiteral::Property, to enable forward declaration.
- Moved around some auxiliary enums.
