c9904976f9 Simplify isolates access during stack iteration (WAS: Move SafeStackFrameIterator::active_count_...) 
While trying to fix Mac and Windows versions for this change:
http://codereview.chromium.org/6771047/, I figured out, that we
already store an isolate in StackFrameIterator, so we can use it in
frame objects, instead of requiring it from caller.

I've changed iterators usage to the following scheme: whenever a
caller maintains an isolate pointer, it just passes it to stack
iterator, and no more worries about passing it to frame content
accessors.  If a caller uses current isolate, it can omit passing it
to iterator, in this case, an iterator will use the current isolate,
too.

There was a special case with LiveEdit, which creates
detached copies of frame objects.

ef06ab5f3e Enable optimizing JSFunctions that are in new-space. 
It avoids strange performance behavior where hot functions do not
get optimized if there is no GC to promote them, and it does not seem
to hurt us otherwise.

4c8fbaffa1 Move stack check patching to the architecture dependent deoptimizer 
files. On ARM it is not enough to iterate the relocation information
because that will only give us access to the constant pool and not to
the place in the instruction stream where the target in the constant
pool is called.

ec16aa9a17 Do not optimize functions which are in new space. 
If there are many shortliving closures, they pollute sampler window and
delay optimizations of functions which should be optimized.

69d6c0bb61 Collect only optimizable function samples. 
Keep track of the ratio between JS and non-JS ticks and use this ratio to adjust the lookup threshold. (Also add support to trace compilation statistics.)
