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.

Added quoting of the name of the ref property using {"ref":1} instead of {ref:1}. The Chrome C++ JSON parser implementation requires quoted property names.
Changed the JSON format for non finite numbers. The previous formatting using NaN, Infinite and -Infinite caused the Chrome C++ JSON parser implementation to fail. Values "NaN", "Infinite" and "-Infinite" (incuding quotes) are now used.
Reverted changes to DebugLookupResultValue (runtime.cc) from http://codereview.chromium.org/17377 . The change caused callback into Chrome with the current V8 context expected to have a DOM Window global object. This is not the case when the debugger context is the active context.

Added handles to the mirror objects. When a mirror for an object is created
...
it is assigned a numeric handle. Handles are used to make a 1:1
correspondence between objects and mirrors. Currently the mirrors are
cached in a JavaScript array and when creating a mirror this cache is
checked to see if a mirror already exists for the object. This cache is
cleared when leaving the debugger.
Changed the serialization format to take advantage of these handles. When
an object is serialized referenced objects are represented just by their
handle id serialized as '{ref:<handle>}'. During serialization the
referenced handles are collected and the serializer can provide a
serialization of all the referenced objects.
Removed the special handling of array properties. Indexed properties and
the length property are now rendered as named properties in the
serialization.
Removed the special serialization handling of RegExp properties. The
properties 'source', 'global', 'ignoreCase' and 'multiline' are serialized
with the rest of the properties.
Changed a lot of tests to handle the changed format.

Changed the serialization format to take advantage of these handles. When an object is serialized referenced objects are represented just by their handle id serialized as '{ref:<handle>}'. During serialization the referenced handles are collected and the serializer can provide a serialization of all the referenced objects.
Removed the special handling of array properties. Indexed properties and the length property are now rendered as named properties in the serialization.
Removed the special serialization handling of RegExp properties. The properties 'source', 'global', 'ignoreCase' and 'multiline' are serialized with the rest of the properties.
Changed a lot of tests to handle the changed format.

Fix issue 191:
...
http://code.google.com/p/v8/issues/detail?id=191
Accessor setters should not be called for eval-introduced context
extension objects.
This change fixes the issue, but I think it is time to separate out
the lookup routines for eval-introduced context extension objects.
There is no reason to use the general lookup routines for this. I'll
do that in a separate changelist.

Refactored the mirror representation of properties. Removed the AssessorMirror and InterceptorPropertyMirror and moved all reflection for properties to PropertyMirror. From a PropertyMirror it can be checked whether a property has getter/setter defined in JavaScript and information on the getter/setter functions are now available. If calling the getter resulted in an exception this is reflected as well.
...
Properties from interceptors are also reflected through PropertyMirror as the distinction did not make sense seen from a JavaScript debugging perspective. The isNative function on a PropertyMirror can be used to check whether a property is defined natively by the host (or V8).
Simplified the local property lookup in the debug runtime call to just call GetProperty as the property is known to be a local property.

This can lead to large objects which wastes a lot of space if we normalize properties. We therfore clear the inobject properties when normalizing properties. This is done by adjusting the instance size in the new map and overwriting the inobject properties with a filler.

Refactored the recording of source position in the generated code. The code generator now has two methods
...
void CodeForStatement(Node* node)
void CodeForSourcePosition(int pos)
The first is used to indicate that code is about to be generated for the given statement and the second is used to indicate that code is about to be generated for the given source position.
Added position information for some statements which was missing whem.
Updated the code generator for ARM to emit source position the same way as for IA-32.
Added an assert to ensure that deferred code stubs will always have a source source position as if it has not it will take whatever source position before which makes no sense.
The passing test on ARM has only been tested using the simulator.

Introduced a TempAssign utility because I just couldn't watch this anymore. YMMV.
