      [turbofan] Decouple inlining and native context specialization. · 9b14e5bb
      bmeurer authored 
      Retrieve the native context/global object from the Node being
specialized in the JSNativeContextSpecialization and the
JSGlobalObjectSpecialization classes. For this we introduce two
new methods NodeProperties::GetSpecializationNativeContext and
NodeProperties::GetSpecializationGlobalObject, which walk up
the context chain and might in the end take the native context
from the outermost activation (if native context specialization
is enabled). This allows us to run the native context specialization
pass as part of the inlining phase without hacking some of that into
the JSInliner.

Also refactor the NodeProperties::GetSpecializationContext method
that was previously local to the JSContextSpecialization.

Also refactor two other oddities in JSNativeContextSpecialization.

      Drop ambiguous MaybeHandle comparison and hashing ops. · 51fa9e52
      mstarzinger authored 
      The default equality comparison operators and hashing functions for
Handles are ambiguous. The intended semantics might have either been
based on Handle locations or on object identity. This is why such
operators do not exist on Handle. The same argument applies to the
MaybeHandle class as well. Comments in that regard were also added.

      [turbofan] Remove usage of Unique<T> from graph. · 6e65e6db
      mstarzinger authored 
      The usage of Unique<T> throughout the TurboFan IR does not have any
advantage. There is no single point in time when they are initialized
and most use-sites looked through to the underlying Handle<T> anyways.
Also there already was a mixture of Handle<T> versus Unique<T> in the
graph and this unifies the situation to use Handle<T> everywhere.

      [turbofan] Revive the VectorSlotPair and also put feedback on JSCallFunction. · d4f70f8c
      bmeurer authored 
      We resurrect the VectorSlotPair in order to be able to separate the
feedback input for the compiler from the actual type feedback vector
that is required to meet the IC requirements at runtime. This will allow
us to for example use feedback from a different context or divide the
type feedback vector into two separate vectors, without having to touch
the compiler. It'll allow use to load the vector from the shared
function info at runtime, while still consuming feedback in the
compiler (i.e. we don't rely on the feedback vector node to be a heap
constant).
