A 6DOF constraint that constrains all rotation axis in combination with a body that has some of its rotation axis locked would not constrain the rotation in the unlocked axis.
Fixes#109018
Fixed bug in ManifoldBetweenTwoFaces which would not find the correct manifold in case face 1 had 3 or more vertices and face 2 only 2. E.g. for a box resting the long edge of a cylinder this would mean that only a single contact point was found instead of 2 (the other way around would work fine).

It uses the non-aligned version, which on 32 bit platforms usually returns an 8 byte aligned block. We therefore default to 16 byte aligned allocations when the regular new operator is used.
