MIPS: Fix bug introduced by r15640.

This bug causes segfault in the octane benchmark,
because the deoptimization entries do not fit in the
deopt table.
This change increases the table entry size.

Throw if first argument to TypedArray.set is a number.

Further refinement to semantics that I have missed in previous change.
Both Blink and Firefox are permissive with arguments to .set method.
However, when first argument to "set" is a number, all implementations
throw, so that users know that
a.set(0,27)
does not assign 27 to 0th element of a, not 0 to 27th element of a.

[Object.observe] Lazily allocate callbackInfo structure

This patch allows callbacks to lazily allocate the InternalArray which is used to store pendingChangeRecords. This moves some of the expense of observation to the case where changes actually occurred.

When there are no pendingChangeRecords, the callbackInfo structure is a number which is the callbacks priority. Whenever a changeRecord is enqueued to the callback, it "normalizes" to be an InternalArray with a priority property. Immediately before its changeRecords are delivered, it returns to its optimized state.

---
Note: Naming confusion resolved:

This patch corrects some naming confusion in object-observe.js. Previously, we used the terms "callback" and "observer" to mean roughly the same thing, and overloaded the term "observer" to be both the callback itself and the *registration* on a object to observe (which now includes an accept map).

This patch resolves this confusion:

"object" (objectInfo, objectInfoMap): This refers to the observed object and its structures

"callback" (callbackInfo, callbackInfoMap): This refers to the callback to whom change records may be delivered

"observer" (objectInfo.changeObservers): This refers to a registration to observe a given object by a given callback with the specified accept list.

This essentially relands r14930 and r14935 with adaptions to the current

instead of one specialized HAllocateObject instruction, hence creating a

The code previously assumed that an array with fast properties must have

Array.prototype.keys
Array.prototype.entries

Suppress array bounds check for nacl build.

The NaCl and the ARM builder started failing to compile at revision 15593 with spurious array bounds warnings.

The ARM builder will be fixed by updating the cross-compiler version. Since the nacl compiler comes with the nacl toolchain, the warning will be suppressed for that builder.

MIPS: Adjust default Heap sizes.

This change decreases the default Heap sizes on MIPS (sets the

Most MIPS hw has smaller RAM size than 700MB, which can lead
to test failures, if a test does not set the Heap sizes explicitly
