Since we need the notion of a dummy vector ic, we can use that to avoid
a special case of the IC constructor. Also, consolidate the two dummy
ICs into one.

This is the initial (big) step towards a more uniform implementation of
the ToObject abstract operation (ES6 7.1.13), where we have a fallback
implementation in JSReceiver::ToObject() and a fast (hydrogen) CodeStub
to deal with the fast case (we should be able to do more cleanup on this
in a followup CL).  For natives we expose the abstract operation via a
%_ToObject intrinsic, also exposed via a macro TO_OBJECT, that unifies
the previous confusion with TO_OBJECT_INLINE, ToObject, TO_OBJECT,
$toObject and %$toObject.  Now the whole implementation of the abstract
operation is context independent, meaning we don't need any magic in the
builtins object nor the native context.

Revert of [cq] Increase commit burst delay. (patchset #1 id:1 of https://codereview.chromium.org/1258193003/)

Reason for revert:
Committing more than one CL at a time led to some odd buildbot behavior on the console (probably an independent bug).

Add factory methods for different types of LinkageLocations, and ensure that
accesses to the underlying data in the location are classified by type and
funneled through explicit accessors.

Also change the representation of LinkageLocation to use a BitField rather
than using a reserved section of the integer range.

   When enabling the v8 profiler (Using the following command parameters: --js-flags=--prof)
   or vtune profiling in chromium. it will break. This failure is introduced by this CL:
   https://codereview.chromium.org/1218863002.

   The reason is that V8 will enable the JITted code logging if --prof is set for V8. And under
   this condition, the function Logger::LogCodeObjects() will be invoked and it will trigger a
   mark-compact GC when deserializing the snapshot. This GC will use MemoryReducer to post a
   delay task by invoking V8Platform::CallDelayedOnForegroundThread() function. But at this point
   V8 isolation is still under initialization and the PerIsolationData of this isolation has not
   been created. (isolation_holder.cc:39~40 line). This leads to V8Platform::CallDelayedOnForegroundThread()
   failure because of segment fault.

   According to my understanding, I proposed the following fix. If the heap deserialization has not
   be completed, it does not post the delay task for next GC.

This is the first step in cutting the Gordian linkage/linkage-impl knot.

This basically changes the axis along which we organize call descriptor
building logic from having platform-specific files dedicated to all call
descriptor types to having call-descriptor-type-specific files that have

The next step is to factor the JS, code stub, and runtime call descriptors
similarly, dumping them into:
  compiler/js-linkage.cc
  compiler/runtime-linkage.cc
  compiler/code-stub-linkage.cc

 or, alternatively, all of them just into compiler/js-linkage.cc.

This also anticipates a wasm-linkage.cc file in the future.

All runtime function get a context anyway, which is the same as the
explicit one in case of DeclareGlobals and DeclareLookupSlot. So
we can remove the additional parameter there.

As an additional bonus, improve the runtime interface to DeclareLookupSlot.
