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.
