372087a5bc Fix again HeapEntry size problem, now platform-independent way. 
Rico noticed that V8 ARM builder also fails on HeapEntry size
assertion. As MSVC-specific way of fixing the problem causes
aliasing problems on G++, I re-implemented conversion using
unions. And #ifdefs are gone!

1cfc63cf8a New heap profiler: implement fast retaining sizes approximation. 
Approximation is done by building a dominators tree for the heap graph.
Dominator nodes and retained sizes are serialized into JSON.

Removed:
 - reachable size (it is useless, after all);
 - HeapEntryCalculatedData (size is now stored in the node, retaining
   paths in a hash map);

051f314a99 New heap profiler: include all heap objects and refs into snapshot. 
Otherwise, retaned memory sizes are not precise. This increases size
of heap snapshot, I will deal with this later. Heap objects and
references previously missing in snapshot are now marked as 'hidden'.
That means, they not shown to user, but participate in sizes
calculation.

Other small changes:
 - added 'shortcut' graph edges: e.g. to pin global objects on top
   level;
 - meta-information in JSON snapshot is no more double encoded.

I observed that used heap size provided by Heap::SizeOfObjects() is
usually about ~10% bigger than the number calculated by summing up
heap objects sizes.

This aligns DevTools Timeline stats with Heap profiler stats.

20938fc53c Attempt to collect more garbage before panicking with out of memory. 
Currently weak handles retain an object for another GC round (oftem times,
major GC round.)  Instrumenting Chromium shows that navigation leaves
many global objects which are only collected in next go.  Let's
attempt to collect more garbage when approacing OOM condition.

This is a better version of rolled out r5455: now it's correctly
rebuilds object groups between additional GCs.

1. Generate a random 32-bit value at compilation time.
2. XOR the 32-bit constant with the random value.
3. Emit the resulting immediate value along with the XOR operation to generate the original value.

e6b33bd20b Support profiling based on linux kernel performance events. 
Since 2.6.31 perf_events interface has been available in the
kernel. There's a nice tool called "perf" (linux-2.6/tools/perf) that
uses this interface and provides capabilities similar to oprofile. The
simplest form of its usage is just dumping the raw log (trace) of
events generated by the kernel. In this patch I'm adding a script
(tools/ll_prof.py) to build profiles based on perf trace and our code
log. All the heavy-lifting is done by perf. Compared to oprofile agent
this approach does not require recompilation and supports code moving
garbage collections.

Expected usage is documented in the ll_prof's help. Basically one
should run V8 under perf passing --ll-prof flag and then the produced
logs can be analyzed by tools/ll_prof.py.

The new --ll-prof flag enables logging of generated code object
locations and names (like --log-code), and also of their bodies, which
can be later disassembled and annotated by the script.

9673ee5d59 Get rid of requested size in RetryAfterGC. 
This was only used by Heap::CollectGarbage to check if after GC
available space is bigger than was requested, but nobody checked
the value returned by Heap::CollectGarbage, so requested size
was efficiently unused.

However, it may trigger spurious out of memory exceptions if requested
size is big enough.

cabe82959f Try to simplify the semantics of the profiling code by making 
sure to suspend the thread (if necessary) on mac/win32 before 
reading the VM state.

Avoid dealing with signals delivered to non-VM threads on 
linux no matter if we're profiling or not.
