3699616609 Rename SeqAsciiString 
This is a straight rename:

NewRawAsciiString -> NewRawOneByteString
SeqAscii -> SeqOneByte

SeqOneByteString cannot yet take non-ascii data.

4d23256cf9 MIPS: Add code again to allow reclaiming old unexecuted functions. 
Port r12898 (69ff6e50)

Original commit message:
When code objects in the heap for FUNCTIONs and OPTIMIZED_FUNCTIONs are marked by the GC, their prologue is patched with a call to a stub that removes the patch. This allows the collector to quickly identify code objects that haven't been executed since the last full collection (they are the ones that sill contain the patch). The functionality is currently disabled, but can be activated by specifying the "--age-code".

That change added a test which called the handlified version of JSObject::SetElement and didn't check the return value, but that method has a MUST_USE_RESULT annotation. This change removes the annotation for consistency with other handlified static methods (like SetProperty).

5e7b796479 Object.observe: Move notification of JSArray length changes to JSArray::SetElementsLength 
The previous implementation in Accessors::ArraySetLength failed when array length was set through StoreIC_ArrayLength. But that stub and the accessor both delegate to JSArray::SetElementsLength, so moving the code there allows notifications to be sent in both cases.

To preserve ordering guarantees during end-of-turn delivery, Object.deliverChangeRecords needs to remove the delivered-to observer from the list of active observers.

Wins back ~1500 points on Octane/Gameboy that we lost with
https://codereview.chromium.org/11365111 (CL 12900), presumably
by lowering register pressure and/or handlification overhead.
Hopefully benefits other regressions as well.
