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.

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.

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.

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:

running tests on Windows. This requires
Added the option --win-error-box to enable general protection fault
message box which can be convenient when debugging failing tests on
Windows.
Added crash detection when running tests on Windows. The output
is not fully polished but crashed indications are printed for the
different progess indicators.
Changed the OS::Abort on Windows from generating a "crash" (int3)
to calling abort(). This is to avoid tests which are known to fail
with out of memory errors to be detected as crashed tests.

- 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.

/GF) in both SCons and Visual Studio build. There is not mesurable difference
neither in speed nor in code size.
Added whole program optimization to the SCons release build. This clutters the
linking of the samples a little with the option /LTCG. This option is not
strictly needed for linking, but if it is not specified the linker complaints
as it can see object files compiled with /GL and then restarts itself with
/LTCG which dosen't look very pretty.
