Sampling rate is now calculated as total number of samples divided by profiling time in ms. Before the patch the sampling rate was updated once per 100ms which doesn't have any obvious advantage over the simpler method.
Also we are going to get rid of the profile node self and total time calculation in the v8 CPU profiler and only expose profiling start/end time for CpuProfile and number of ticks on each ProfileNode and let clients do all the math should they need it.

Revamp v8_optimized_debug options
This patch changes the definition of v8_optimized_debug==1 to match the release-mode compiler optimization settings (generally, going from -O1 to -O3 on Linux, similar switches for Mac/Win). This produces a minor speed up on Linux, but significant speedups on Mac and Win. This may make it much harder to debug, though.
It also adds a v8_optimized_debug==2 that, in addition to the compiler optimizations, undef's DEBUG and defines DEBUG. This leaves V8_ENABLE_CHECKS alone (so that the assertions are still enabled), but otherwise basically matches a release mode build.
Builds with v8_optimized_debug==2 roughly match a Release mode build for speed; the V8_ENABLE_CHECKS checks appear to have minimal performance impact (maybe 5-10%, unlike what was previously thought). In addition, switching from the previous optimization settings makes a significant improvement on Mac and Win (50% or more), and switching from DEBUG to NDEBUG makes a significant improvement (another 50% or more).
Note that using v8_optimized_debug==2 may also cause some v8 tests to fail. This is currently is believed to be acceptable.

Logger: introduce abstract interface for CodeEvent listeners.
New abstract class CodeEventListener was created.
CodeEventLogger which is the base class for Jit, LowLevel
and CodeAddressMap loggers was inherited from CodeEventListener.
CodeAddressMap class was moved to serializer.cc because serializer is the only user for it. Actually it collects code names and pushes them to the standard log as SnapshotCodeNameEvent. So I extracted this code into separate function CodeNameEvent. It happens that this method works only when Serializer serializes an object. So I added direct log call there.
CodeEventLogger class declaration was moved to the header
because CodeAddressMap needs it.
The code for the nested class CodeEventLogger::NameBuffer was left in the cc file.
CpuProfiler now is inherit CodeEventListener but not used
the loggers infrastructure yet due to the complex initialization schema. I'd like to fix that in a separate cl.

Lazy call to custom stack trace formatting using Error.prepareStackTrace.
This enables custom stack trace formatting for stack overflow.
A consequence is that stack trace formatting is now easily observable,
but we already established that the default stack trace formatting can
be observed anyways. It is only triggered by the .stack getter, and
it has to be explicitly called, (e.g. not implicitly after GC).

The stand-alone test driver is changed a bit:
- Don't use the errorMessage list. It is used differently in the embedded driver. There it collects parser errors - instead of failure messages.
- Remove html links in description texts. Some test descriptions print a web reference.
The migrated tests fall into 3 categories:
1. Tests outside fast/js
2. Tests that print FAIL messages (and also expect those) - these tests should be examined later if they make sense at all

move 32 bit heap hint on sunos
Setting the V8 heap at or near 0x20000000 on 32bit sunos only allows
512 MB of heap space, instead on sunos move this to 0x80000000.
To quote the comment
For our Solaris/illumos mmap hint, we pick a random address in the bottom
half of the top half of the address space (that is, the third quarter).
Because we do not MAP_FIXED, this will be treated only as a hint -- the
system will not fail to mmap() because something else happens to already
be mapped at our random address. We deliberately set the hint high enough
to get well above the system's break (that is, the heap); Solaris and
illumos will try the hint and if that fails allocate as if there were
no hint at all. The high hint prevents the break from getting hemmed in
at low values, ceding half of the address space to the system heap.

Add deopt fuzzer tool.
Can be run as a stand-alone script like run-tests.
Executes first all tests of a given test suite to collect the maximum number of possible deopt points. Runs then a fuzzing phase with artificial deoptimizations triggered during testing.
Works for now with mjsunit and ia32 only.

Factor out common code from platform-specific deoptimization. Fix Deoptimizer not to need to partition functions, but revoke their code before patching, allowing deoptimizing_code_list to be removed from Code; Add DeoptimizeCodeList API to deoptimizer, which works on a ZoneList<Code*>.

Extend existing blink test expectations for slow tests.
The test plugins/js-from-destroy.html has crash and timeout expectations for some configurations but not on windows release. Add 'slow', since there is a timeout only on the v8 waterfall and only for windows release.

Avoid adding HWrapReceiver during graph building.
This adds an early check to the graph builder which prevents adding an
HWrapReceiver instruction if the receiver type is already known at graph
building time. Also HAllocate no longer unnecessarily postpones setting
it's type until type inference but sets it right away. These changes are
in preparation for escape analysis.

Fix call stack sampling for the case when native callback invokes JS function
The SafeStackFrameIterator used by CPU profiler checked if Isolate::c_entry_fp is null and if it is not it would think that the control flow currently is in some native code. This assumption is wrong because the native code could have called a JS function but JSEntryStub would not reset c_entry_fp to NULL in that case. This CL adds a check in SafeStackFrameIterator::IsValidTop for the case when there is a JAVA_SCRIPT frame on top of EXIT frame.
Also this CL changes ExternalCallbackScope behavior to provide access to the whole stack of the scope objects instead of only top one. This allowed to provide exact callback names for those EXIT frames where external callbacks are called. Without this change it was possible only for the top most native call.
