7be18f702b make DateParser::TimeComposer handle 1-2 digits millisecond values 
see http://code.google.com/p/v8/issues/detail?id=944
This patch makes DateParser::TimeComposer process times that have
millisecond values with only 1 or 2 digits.

Without this patch, Date.parse("2010-11-25T22:02:30.5") returns
1290690150005 and
Date.parse("2010-11-25T22:02:30.5") == Date.parse("2010-11-25T22:02:30.005")
evaluates to true.

With this patch, Date.parse("2010-11-25T22:02:30.5") returns
1290690150500 instead, and
Date.parse("2010-11-25T22:02:30.5") == Date.parse("2010-11-25T22:02:30.005")
evaluates to false.

be0f740d99 Landing for Justin Schuh. 
Seed the random number generator in Windows with rand_s 

This is a quick fix for m9. It works on Windows Chrome because the random device is already initialized before permissions are dropped for the Chrome sandbox. The same trick isn't possible on Linux or Mac. 

I think the long-term solution is to provide an interface for supplying v8 with a true random number generator. Then Chrome can just hook up the generator from base/rand_util.h

4c6f79ecec Fix crashes during GC caused by partially initialized objects. The 
inline allocation code used the expected number of properties to
calculate the number of inobject properties for an object instead of
getting the actual number from the initial map.

It is safer to use the inobject property count from the initial map in
any case because that is the amount the instances will get. I think
this disconnect got introduced when adding shrinking of objects.

Unfortuntely I haven't been able to create a simple reproduction for a
test case but this fixes the webpage that exhibits the crash. I'll see
if I can create a reproduction tomorrow.

assertion. As MSVC-specific way of fixing the problem causes
aliasing problems on G++, I re-implemented conversion using
unions. And #ifdefs are gone!

Approximation is done by building a dominators tree for the heap graph.
Dominator nodes and retained sizes are serialized into JSON.

 - reachable size (it is useless, after all);
 - HeapEntryCalculatedData (size is now stored in the node, retaining

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.

7ac932c088 Add bignum fall-back when the fast dtoa doesn't succeed. This removes Gay's dtoa for the double->string direction. We still need it for the string->double direction.

a298666fae Store script's line ends in copy-on-write fixed array. 
This allows to remove explicit copy from line ends JS accessor which is used for formatting of stack traces.

Eager copying of line ends array might cause multiple full GC collections for huge scripts (e.g. scripts generated by GWT compiler with PRETY preset).
