5392e94e8b ClearTypeFeedbackInfo(): context may not be initialized. 
SharedFunctionInfo::ClearTypeFeedbackInfo() wants to compare feedback
to the array JSFunction, but it's called at times when the context
isn't fully initialized. Be cautious about this check.

3d0bf69cd8 Attempt no. 3 to fix Heap::IsHeapIterable and HeapIterator. 
Now we remember new space's top pointer after the last GC to find out if there was a new space allocation since the last GC.

Unfortunately, this not completely safe - the debugger has a callback hook (that can call to JS) at the end of the GC epilogue that can in theory allocate and possibly make the heap non-iterable. We can only hope this does not happen.

0829572ee8 Revert "Rename target-specific binaries built for host." 
The Android build system support for gyp has been fixed to handle
target-dependent host binaries correctly without requiring them to
include the target architecture in the name. Remove the suffixes to make
referring to these targets simpler again.

This reverts r14209.
