Bug in bullet header

[Xrysnow]

The macro

cocos2d-x-3rd-party-libs-bin/bullet/include/bullet/LinearMath/btScalar.h

Line 440 in 59f0333

#define SIMD_2_PI btScalar(2.0) * SIMD_PI

is missing parentheses, and therefore

cocos2d-x-3rd-party-libs-bin/bullet/include/bullet/LinearMath/btScalar.h

Line 443 in 59f0333

#define SIMD_DEGS_PER_RAD (btScalar(360.0) / SIMD_2_PI)

and

cocos2d-x-3rd-party-libs-bin/bullet/include/bullet/LinearMath/btScalar.h

Line 488 in 59f0333

SIMD_FORCE_INLINE btScalar btDegrees(btScalar x) { return x * SIMD_DEGS_PER_RAD; }

are totally wrong.
