If the CallIC collected a known target function for a callsite, add
a runtime check to ensure that the feedback remains the same and
specialize the JSCallFunction node to the known target function so that
inlining and typed lowering can pick up the feedback.

This moves the cctest file for the interpreter to live in the same
namespace as the components it is testing. Hence we can avoid the
forbidden using directives pulling in entire namespaces.

Besides making SetSuperProperty and others return Maybe<bool>, this CL
also fixes some parts of my previous refactoring of SetProperty and
others: It doesn't make sense to take both a language_mode and a
should_throw argument.  A strict language_mode should imply
THROW_ON_ERROR.

Adds new Guard[Type] common operator, which takes value and control
inputs and records a guaranty that a certain value has a certain type
in that control path.  This is some kind of ad-hoc SSI similar to what
we have to do in Crankshaft in some places.

Also introduces an ObjectIsNumber simplified operator, which checks
whether a certain value is a number (either a Smi or a HeapNumber).

This doesn't yet support transitioning stores to double fields, which
require support for allocating mutable heap numbers.

In order to properly (lazy) bailout when converting the receiver for
sloppy mode functions (using the newly added JSConvertReceiver
operator), we need to have a bailout location right before every call
(also right before every %_Call and %_CallFunction), otherwise if the
JSConvertReceiver just reuses the lazy bailout frame state from the
JSCallFunction node, it will skip the whole function in case of lazy
bailout.

Note it should be impossible to trigger this currently because we do not
yet support AllocationSite code dependencies in TurboFan, which can
trigger this kind of lazy bailout; therefore it's not possible to write
a regression test (yet).

We have plans to create more ICs, and we are out of bits to represent the Kind
in the flags field of the code object. The InlineCacheState can lose a bit
because it no longer needs the DEFAULT state. That state existed as a way to
detect errors where code incorrectly looked at a vector IC stub's
InlineCacheState instead of correctly determining said state from a glance at
the vector. This really isn't a danger anymore.

So, with the horse trading, we could now represent up to 32 code kinds.

we may introduce moves that are redundant in the context of
moves on subsequent instructions. Currently, we only detect such
redundancies by allowing moves to skip over Nop instructions (true
nops, with no input/output). We can also skip over other cases, for
example over constant definitions (nop with an output), since whatever
moves happen above it do not influence the instruction's outcome.

We may be able to handle other cases, too - in subsequent CLs.

This requires copying usage flags from the outer scope to the
arrow scope upon encountering the arrow token.

In order to properly pass-on the calls_eval bit, now record
that bit on script scopes just like everywhere else, and add
necessary code to scopes.cc to handle that change in behavior.

Also factored out scope flag propagation to its own method to
make the call site simple (though note that only the eval
bit makes any difference for arrows).

The fix is to broaden the set of cases for when NeedsHomeObject()
returns true. Note that this is broader than it needs to be (since,
e.g., non-arrow function scopes inside a method can't reference
super). But we don't track the types of inner scopes at the moment,
so this is the best we can do.
