This fixes warning on android_arm build.
Previously the compiler complained about a check that can never be true.
See second check below(index is size_t type, FIRST_SPACE=0):
if (index > i::LAST_SPACE || index < i::FIRST_SPACE)
And make the code easy to understand.

This is the first step towards unifying external and on-heap typed arrays.

The end-state will be that this base pointer either points to the on-heap values
or to the externally allocated array buffer.

This invariant will save us some head ache.
The changes to test-debug/DebugStub is due to the fact that it abuses
the ability to set break points in code that has no debug break slots.
This is now no longer possible.

Using TranslatedState and friends is too expensive compared to the low
level TranslationIterator, because some code (i.e. in Speedometer)
depends on the OptimizedFrame summary/function listing to be very fast.

In ES6, the TypedArray constructor can be called either with an
array-like object or an iterable. The code previously handled
only array-like objects. This patch switches to supporting
iterables while throwing in an optimization to make Arrays
get allocated the old way, without an extra copy.

The TryLowerDirectJSCall method tried to lower to a direct JavaScript
function call depending on the type of the receiver, but only if the
target is a cosntant JSFunction. Since this depends on types and is not
required for correctness, it shouldn't be part of generic lowering
anyway. So this functionality was moved to typed lowering instead, and
we use proper types for the target instead.

This hack doesn't help currently, since it only applies to asm.js where
we do function context specialization and there we already have a
canonicalized context (and the CodeGenerator materializes that from the
frame).

Apparently the *RealNamed* API methods only have named variants, but were always used by the embedder to find elements as well. We'd never find them though, since we wouldn't even look
there.

This CL ensures we check whether the name is actually an array index.

I guess for all named API functions we should assume they are used similar to o["name"] where name could also be a number... At least we should make it uniform between embedder and V8. This matches us up with their expectations for now...

      The strong-object-set-proto test cases will throw one expected exception
      and the exception message should include the source position in the JS
      file. But crankshaft compiler does not generate the source position for
      it when creating the flow graph by default. The source position information
      is always zero. So it failed when comparing with the reference file.

      If we use crankshaft compiler on IA32 platform to run this test case, it
      has the same failure.

      we will open these test case for x87 once turbofan for X87 is enabled.
