b2f0dc3542 Don't do local lookup on global object as those (currently) are not JITed anyway.

dfbc850ebc Revert revision 2108. This brings back the changes 
submitted in revisions 2093, 2094, 2099, and 2106.
There's no evidence that supports that these changes
should be the cause of the unexplained performance
regressions on the intl2 and DHTML page cyclers.

84c09c6de4 Experimental revert of revisions 2093, 2094, 2099, and 
2106 to try to isolate a performance regression on the
page cyclers.

I'll roll the changes back in if this doesn't fix the
regression.

be11c4e979 Patch by Craig Schlenter. See http://codereview.chromium.org/118153 
Change stack alignment on linux to 16 bytes to keep gcc 4.4 happy. 
This fixes the mksnapshot segfault without requiring -fno-tree-vectorize
which just avoided the problem by not generating code with movdqa.

0a0ede0716 Fix the issue with layout tests. 
The problem was I incorrectly treated NULL result as failure to fetch
a property with a getter.  However, if getter returns zero, it is
manifested as NULL pointer (see added test case).

Good news: that gives another boost as before this CL if getter returned
0, I did another slow lookup.

06fdc01543 In case of holder with fast properties that allows to fetch the property 
immediately if holder has this property or saves binary search on holder if
property doesn't belong to holder.  Of course, in the cases when named getter
returns nothing.

That gives ~20% for dom benchmark/Document Object String Get, speeds up overall
dom_perf (not dramatically) and overall score for peacekeeper.  Strange, but DOM
part of peacekeepr runs somewhat slower.

0fcedde224 Fix determining of JS lower stack bottom used in profiler's JS stack tracer to work with Chromium. 
My assumption that log initialization happens somewhere near the stack's bottom is true for V8's sample shell but isn't true for Chromium, causing many otherwise valid stack addresses to be thrown out. The solution proposed is to save stack pointer value for the outermost JS function in ThreadLocalTop similar to c_entry_fp.

Implemented only for IA-32. Currently I'm not dealing with profiling on ARM and x86-64 anyway.

a019501be2 Change the handling of the debug break stack guard. The debug break is no longer ignored when hit inside "system" JavaScript. The reason for this is twofold: 
* Running "system" JavaScript with the debug break flag active leads to slow running code while waiting for the break in non "system" JavaScript (one exception to this it is to try to avoid breaks in the clear mirror cache JavaScript code called when leaving the debugger).

* If this happens while processing RegExp running in native code an infinite loop is created as the stack guard handler for RegExp does not move execution forward

Fixed a GC bug in the interrupt handling for RegExp running in native code.

Added test of debug break while in debug message handler callback and debug break while executing a RegExp.

795ba99117 Handle filling up of memory buffer to make log processing in DevTools Profiler easier. 
When profiler's memory buffer is filled up, profiling is stopped and it is ensured that the last record in the buffer is "profiler,\"pause\"" thus making the end of profiling session explicit. Otherwise DevTools Profiler would need to guess whether the current profiling session has been stopped.

Tested with Chromium.

58aa022d6c Tiny fix: initialize TickSample::frames_count with 0. 
I suggest that the lack of initialization causes issue 358 to happen. In Profiler::Disengage an empty TickSample is inserted in order to wake up the Profiler thread. Issue reporter claims that crash happens in LogTickEvent function. My guess is that frames_couint receives a wild value.

e48095b87c Implement a dynamically growing memory log buffer with an upper limit. 
The goal of this change is to allow longer profiling sessions and preserve memory when profiler isn't started. The buffer starts with 64K and grows until it reaches the upper limit, which is currently set to 50MB --- according to my evaluations, this is enough for at least 20 minutes of GMail profiling. As we're planning to introduce compression for the profiler log, this time boundary will be significantly increased soon.

To make possible unit testing of the new component, I've factored out Logger's utility classes into a separate source file: log-utils.h/cc. Log and LogMessageBuilder are moved there from log.cc without any semantical changes.

46eb69656d Remove duplicate line in benchmarks/base.js 
This resolves issue 356 (http://code.google.com/p/v8/issues/detail?id=356) thanks to bitRAKE. Changed benchmark version number from 4 to 5 resulting in updates to base.js, README.txt and revisions.html.
