This removes support for accessing super properties (load, store & call)
from the {FullCodeGenerator}. Consequently optimized code containing
such constructs must use the {BytecodeGraphBuilder} and can no longer
use the {AstGraphBuilder} for graph building.

The current Array.prototype.sort implementation is pretty sensitive to
compiler changes, i.e. switching to I+TF completely, so refactor it a
bit so that it can stay with FCG+CS for now.

Middle-term the Array builtins need to be refactored to TurboFan
builtins anyways.

In the current implementation, WasmInstanceWrapper is allocated after the imports for the instance are processed, and before the InstanceFinalizer callback is associated with the instance. This raises the possibility of triggering a gc in the middle of the instantiate flow which is incorrect.

Revert of [typedarrays] remove invalid optimization in NAMEConstructor() (patchset #1 id:1 of https://codereview.chromium.org/2544503002/ )

Reason for revert:
Speculative revert for causing timeouts on Win Debug gpu fyi bot

Nothing else looks even remotely relevant in the list of changes.
Will reland if this doesn't fix the issues.

BUG=670396

Original issue's description:
> [typedarrays] remove invalid optimization in NAMEConstructor()
>
> Before, we were treating objects with the builtin ArrayValues iterator
> method as array-like, where the iterator would iterate through to the
> full length of the object.
>
> This optimization was not sound, because it does not ensure that the
> next method hasn't been modified. Even if it hasn't been modified,
> it's entirely possible to be modified during iteration. Thus, this
> optimization has been removed due to its observability.

This apparently gradually fell out of use after the more general
Token::IsIdentifer was introduced, and whoever left last forgot to
turn out the lights.

The only remaining use was in an assertion in DeclareLabel, but
meanwhile DeclareLabel is only called if IsIdentifier. I added re-formulated assertions, just in case.

This enables {FLAG_debug_code} by default in debug builds. The advantage
is that generated code contained within the snapshot will contain such
debug code. Before we would only get coverage for these pieces with the
no-snapshot builds, which have a meager coverage. One can still pass the
inverse --no-debug-code flag to ensure generated code remains readable
within debug builds as well.

Since we don't pass references to this constant to the DCHECKs any more
(see http://crrev.com/2524093002), the constant can now be initialized
in the header, reducing code size and increasing performance.

Before the mentioned change in CHECK/DCHECK, this caused link errors.

Crankshaft has this highly unpredictable performance cliff around the
"Unsupported phi use of const or let variable", which is due to the
fact that Crankshaft refuses to do hole checks (for a couple of
reasons). So ideally we should not even try to send any lexically bound
variables to fullcodegen+Crankshaft, but instead give them to Ignition
and TurboFan.

This CL only adds the appropriate check to the AstNumbering, but doesn't
remove the functionality from fullcodegen/Crankshaft yet. This would be
step two in case this CL sticks. If you see any major performance
regressions with this CL in the range, just revert it and ping me.

See Node.js issue https://github.com/nodejs/node/issues/9729 for
additional information.
