vegorov@google.com 77c26187f2 Support allocation sinking for compound objects. 
- Improve escape/alias analysis:
-- Storing an object into a field of another object does not mean that this object escapes (or has aliases) as long as that object does not have any loads from the same place;
-- Places like X.f and Y.f don't alias if X and Y are two different allocation instructions even if X and Y themselves potentially have aliases;
-- Improve precision of alias analysis for indexed properties;

- Support dematerialization and rematerialization of objects that are referenced by other dematerialized objects.
-- Use fix-point algorithm to collect candidates for allocation sinking;
-- Support aborting unsuccessful allocation sinking.

johnmccutchan@google.com efc684e4a8 Move some isolate state setup from C++ code to JumpToExceptionHandler stub 
This change means that the isolate's top exit frame info and vm tag will only be updated after setting the frame pointer.

This is step one in a series of changes to allow the profiler to walk the stack when there is no frame pointer.
