3a472fada8 Basic infrastructure for fast two-pass compilation. A CFG is 
generated in one-pass from the source AST, code is generated from the
CFG.  Enabled by the flag --multipass and disabled by default.

Rudimentary and currently only supports literal expressions and return
statements.  There are some other known limitations (e.g., missing
support for tracing).

cffc051177 Avoid dictionary expansion during bootstrapping. 
Allocate the code stubs dictionary and non monomorphic cache dictionary with an initial size which avoids these dictionaries to be expanded during bootstrapping. This gets rid of 9 dictionary expansions during bootstrapping.

Preallocate the dictionary when normalizing an object to a size sufficient for holding the number of properties which is expected to be added to the object. This is used when ceating an object from an object literal boilerplate where multiple properties are known to be added.  This gets rid of 10 dictionary expansions during bootstrapping.

There are now 3 dictionary expansions left during bootstrapping.

98425a31f1 Speed up CalledAsConstructor. 
Changed CalledAsConstructor to process the raw runtime stack directly,
rather than using a StackFrameIterator.  Using an interator turns out
to be quite expensive and the vast majority of the work done is not
relevant to deciding if we've been called as a constructor.

This speeds up getElementById by ~13%.

e97554ed10 Add generic V8 API functions for controlling profiling aspects. 
As we'll have several aspects of heap profiling, it is more handy to control them using binary flags than by individual functions. CPU profiling represent just a particular aspect to control, so {Pause,Resume}Profiler and IsProfilerPaused are only left for compatibility.

For now, PROFILER_FLAG_HEAP_STATS and PROFILER_FLAG_JS_CONSTRUCTOR are equivalent, but later will be split.

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.

60bdcf9e01 Fix issue 410: test-log/ProfLazyMode flakinness under Linux. 
I found two causes of flakinness:
 - SIGPROF signal isn't delivered to a process;
 - Profiler thread (the one that retrieves tick events from
   the queue and writes to log) doesn't get a CPU;
Both are fixed.

The script from bug description with run count increased to 200 runs without any test failures.

OS X and Windows are unaffected because they don't use signals mechanism.
