73b217fb07 Apple contribution for OSX SSE and iOS NEON optimizations unit tests, thanks to Jordan Hubbard, Ian Ollmann and Hristo Hristov.
For OSX:
cd build
./premake_osx xcode4
for iOS:
cd build
./ios_build.sh
./ios_run.sh

Also integrated the branches/StackAllocation to make it easier to multi-thread collision detection in the near future. It avoids changing the btCollisionObject while performing collision detection.

As this is a large patch, some stuff might be temporarily broken, I'll keep an eye out on issues.

710954d772 Constraints can override their own number of solver iterations (either more or less than the default) or leave it default (-1)

07f51390ea Fix for the non-virtual implementation of btGeneric6DofConstraint (mainly for Cell SPU purposes):
Need to explicitly call testAngularLimitMotor(i);, because it cannot be called during 'getInfo1', because m_rbA and m_rbB is not available.

9acb3d1805 Added some improvements on Bullet serialization:
Introduced generated unique id's, instead of the pointer address to avoid 64bit->32bit truncation issues
Use serializer->getUniquePointer instead of directly using a pointer

moved  ChunkUtils::getNextBlock to bFile::getNextBlock.
Moved 'TEST_BACKWARD_FORWARD_COMPATIBILITY' to bDNA.cpp. Enable the define for further testing of .bullet format
Removed duplicate definitions and use the one in LinearMath/btSerialization.h

add btTriangleInfoMap pointer to btBvhTriangleMeshShape, so we don't need to use the 'userpointer' anymore
preparation for serialization of btTriangleInfoMap.

d4c3633405 Get rid of btSolverBody and use btRigidBody directly. btSolverBody didn't improve performance after all, due to random-access
Tweak the BenchmarkDemo a bit: 

1) disable deactivation in graphical mode
2) add some settings that increase performance in the BenchmarkDemo2 (1000 stack) from 35ms to 15ms on this quad core (at the cost of a bit of quality)
