As originally implemented, a SingleNameBinding within a BindingPattern
was incorrectly interpreted as an assignment if an initializer was
present and that initializer was itself an AssignmentExpresion.
For example:
let x;
{ let [x = y = 1] = []; }
print(x); // expected: undefined, actual: 1

pattern to account for AssignmentExpressions within SingleNameBindings.

The parser eagerly rewrites destructuring assignments occuring
in formal parameter initializers, because not doing so would
cause the BindingPattern rewriting to be confused and do the
wrong thing.
This change prevents this rewriting from descending into the
bodies of lazily parsed functions.
In general, it's a mistake to descend into the bodies of function
literals anyways, since they are rewritten separately on their
own time, so there is no distinction made between lazily
"throw away" eagerly parsed functions in the temporary parser
arena, or "real" eagerly parsed functions that will be compiled.

When seeing a rest pattern, we used to get the remaining elements from the
iterator by calling %concat_iterable_to_array on it. This was wrong because it
caused an observable [[Get]] for @@iterator (which the iterator may not even
provide).
This CL gets rid of the call to %concat_iterable_to_array and does the iteration
manually in a simple while-loop. It also gets rid of %concat_iterable_to_array
itself because there aren't any other uses of it.

With the recent spec change removing the [[Enumerate]] internal method, we now
have to walk the complete prototype chain. This implies that we call the
[[GetPrototypeOf]] trap on proxies.
As a secondary change we now trigger the [[GetOwnProperty]] trap for the for-in
filter step to see whether the properties are still enumerable. Before we did this
in the key-accumulation phase. This way we slightly reduce the number of traps
invoked. Whilst this is not ideal, it comes closer to the Spec's example
implementation.

Now that ES2015 const has shipped, in Chrome 49, legacy const declarations
are no more. This lets us remove a bunch of code from many parts of the
codebase.
In this patch, I remove parser support for generating legacy const variables
from const declarations. This also removes the special "illegal declaration"
bit from Scope, which has ripples into all compiler backends.
Also gone are any tests which relied on legacy const declarations.
Note that we do still generate a Variable in mode CONST_LEGACY in one case:
function name bindings in sloppy mode. The likely fix there is to add a new
Variable::Kind for this case and handle it appropriately for stores in each
backend, but I leave that for a later patch to make this one completely
subtractive.

We used to emit debug break location on block entry. This cannot be
ported to the interpreted as we do not emit bytecode for block entry.
This made no sense to begin with though, but accidentally added
break locations for var declarations.
With this change, the debugger no longer breaks at var declarations
without initialization. This is in accordance with the fact that the
interpreter does not emit bytecode for uninitialized var declarations.
Also fix the bytecode to match full-codegen's behavior wrt return
positions:
- there is a break location before the return statement, with the source
position of the return statement.
- right before the actual return, there is another break location. The
source position points to the end of the function.

This patch is a workaround to the performance regression caused by
implementing the ES2015 TypedArray prototype chain: Include a
per-TypedArray-subclass length getter so that the superclass getter does
not become polymorphic. The patch appears to fix a regression in the
Gameboy Octane benchmark.
