66083dd05f Adding api to get last gc object statistics for chrome://tracing. 
For dumping the number of objects and size of objects alive after the
last gc into chrome://tracing memory dumps, this CL adds new api to
get these number for each isolate.

Note: Chrome should be run with --js-flags='--track_gc_object_stats
--noincremental-marking' for object tracking.

fe690c3e82 [turbofan] Carefully update frame states during inlining. 
During inlining we should pay attention to only rewire the outer frame
states of the inlinee, but leave any inner frame states of the inlinee
untouched.  Otherwise we might run into trouble once we start caching
graphs, or do getter/setter inlining.

19312c1631 Do not clear stepping after DebugEvaluate. 
Clearing stepping was originally introduced in http://codereview.chromium.org/7889039
But DebugEvaluate now also uses a DisableBreak scope, which makes sure we don't step
inside the evaluated code.
