abc0bd46f6 Add initial version of retainers heap profile. 
The profile is taken together with constructors profile. In theory, it
should represent a complete heap graph. However, this takes a lot of memory,
so it is reduced to a more compact, but still useful form. Namely:

 - objects are aggregated by their constructors, except for Array and Object
   instances, that are too hetereogeneous;

 - for Arrays and Objects, initially every instance is concerned, but then
   they are grouped together based on their retainer graph paths similarity (e.g.
   if two objects has the same retainer, they are considered equal);

1b812fb3b4 Remove explicit include of Chromium's common.gypi from v8.gyp. 
Explicit includes of common.gypi are being deprecated.  Chromium will include
the .gypi files that it needs by asking GYP to force-include them into each
.gyp file that it loads.  See http://codereview.chromium.org/206006.

dfcfacf1f9 Enable -fstrict-aliasing in the GYP build of V8 for the Mac in Release mode. 
-fstrict-aliasing is enabled by mainline gcc at -O2 and higher, but in Apple
gcc, it must be enabled explicitly.  This results in a 1.5% improvement in V8
benchmark scores.

This also removes the -fno-exceptions and -fno-rtti settings from v8.gyp for
the Mac, and removes -fno-rtti from v8.gyp for Linux, because these settings
have become part of Chromium's common.gypi, included here, as of r23304 at the
latest.  The settings in v8.gyp have become redundant.

b77e2354cc Don't use -fomit-frame-pointer to build Mac V8. The Chrome crash reporting 
system can't currently process stacks produced by gcc -fomit-frame-pointer
properly.  The drawback outweighs the 2% performance improvement.  Once
the crash reporting system is able to handle this optimization, it should be
revisited.

d87f83c5f8 Fix issue 427: JS tick processor now works out-of-the-box for Chromium on Windows. 
MSVS names '.map' file using only module's name, so both 'a.exe' and 'a.dll' will have 'a.map' file. To distinguish an originating module, we're now checking for image base which is always 00400000 for .exe files, and not 00400000 for .dlls.

Verified that windows-tick-processor can now process logs from Chromium using .map file generated for 'chrome.dll', an that it still works for V8's 'shell.exe'.

9e8216ef22 Introduce first approximation of constructor heap profile for JS objects. 
It is activated with '--log-gc' flag.

JS object size is calculated as its size + size of 'properties' and 'elements' arrays, if they are non-empty. This doesn't take maps, strings, heap numbers, and other shared objects into account.

As Soeren suggested, I've moved ZoneSplayTree from jsregexp to zone, and removed now empty jsregexp-inl header file.

e0b829b1a5 TickProcessor: more accurate mapping of statically compiled code on Linux. 
'nm' is now called with an option to report function code sizes. Static code entries are restricted to the sizes reported, and the remaining unnamed code is attributed to a library as a whole. This makes reports more accurate, as some functions are tiny, but has chunks of unnamed code behind them.

This change doesn't affect reporting on Windows, as in .map files function code sizes aren't specified.

00b9b2e5e4 Cleanup v8.gyp. This also drops a bunch of unused targets (the shell, d8, 
etc).

There are now two gyp variables to control whether we build snapshots and which
target we are building for.  This allows you to easily cross-compile for arm and
disable snapshots.

Patch by Joel Stanley.
