4cc5c314d1 Profiler tick processor now counts IC ticks on behalf of a caller. 
This is enabled by default. To get back to old behavior, use '--separate-ic' switch.

ddd2ac4015 Refactored command-line options handling in tick processor scripts 
to remove code duplications. This makes easier adding new options.

The code object header size is now added to the size Before ticks the last instructions of a JavaScript functions ended up as unaccounted in the profile.Include ticks in the the last created code object in the profile.Show the unaccounted ticks in the profile as a percentage together with the rest. Added an option to ignore unaccounted ticks in the percentage calculation.

a23fd3284a Added the simplest call stack sampling and call profile in tick processor output. 
Currently only two stack frames are sampled (current function and its caller).

Output of tick processor looks like this:

 [Call profile]:
   total  call path
   15.2%  LazyCompile: am3 crypto.js:108  <-  LazyCompile: montReduce crypto.js:583
    6.5%  LazyCompile: am3 crypto.js:108  <-  LazyCompile: bnpSquareTo crypto.js:431
    2.9%  Builtin: KeyedStoreIC_Generic  <-  LazyCompile: montReduce crypto.js:583
    2.3%  LazyCompile: am3 crypto.js:108  <-  LazyCompile: bnpMultiplyTo crypto.js:415

Tested under Windows, Linux and OS X.

85584333f9 Support for building V8 with MinGW 
V8 can now be build with MinGW. It still fails the following four tests in debug mode:

  mjsunit/parse-int-float
  mjsunit/mirror-array.js
  mjsunit/integer-to-string.js
  mjsunit/regress/regress-114.js

Building with MinGW has been tested with version 5.1.4 using GCC 3.4.5.

In addition to supporting MinGW this change also makes it more explicit which targets needs to link with which libraries.

3835e915c4 Adding src_file_name:line_number into perf log entries for compiled JS functions. 
Thus, instead of the following profiler records:
   1.5%    1.5%   LazyCompile: <anonymous>
we'll now have these:
   1.5%    1.5%   LazyCompile: <anonymous> richards.js:309

Basically, I translated two functions from messages.js into C++.
In the next CL I will update messages.js to use added native functions.

aa8662545a Further minify non-visible JavaScript. 
This imports a Python version of Douglas Crockford's JSMin.  JavaScript files can annotate that they want to be run through the minifier.  Currently debug and mirror are minified.

This results in ~12k savings on the final binary size.

through the API. This allows us to verify state on entry through the API.
In this change verification in the API entry is checking that the current
thread holds the V8 lock when a HandleScope is instantiated if a v8::Locker
has ever been used by the V8 instance.

d7c933e7ae Added support in the profiler for creating 'regions' that cover part 
of the generated code.  These can be used by the profiler to
categorize the ticks that occur within generated code and thereby show
more detailed information about where time is spent in generated code.
For instance, this is what the profiler displayed for a simple regexp
benchmark with irregexp-native before:

[JavaScript]:
   total  nonlib   name
   87.2%   87.2%   RegExp: (?:\w*\W+)*

This is what we can display now:

[JavaScript]:

9d9f608a38 - Added caching of regexp data in the compilation cache. 
- Changed the structure of regexp objects from having two internal
  fields to having a single field containing a fixed array, since it's
  easier to store the whole fixed array in the cache.
- Move printing of the command to after printing std{err,out} in the
  compact progress indicators in the test framework.
