Saran Tunyasuvunakool 215433f5f7 Implement mj_stackAlloc and mj_arenaAlloc alignment using bitwise-and.
This implementation explicitly avoids calling division instructions (which are generally expensive) even when link-time optimization is not active or if the alloc functions aren't inlined for some reason.

Also make mj_stackAlloc cheaper for external callers who may be linking against MuJoCo dynamically (and therefore cannot benefit from inlining).

Yuval Tassa 1dad5993f0 Refactor constraint island representation.
Required for constraint solver islanding.

Replace linked lists with `island_{dof,efc}_{num,adr,ind}`, corresponding to the standard `{rownnz,rowadr,colind}` sparse matrix representation. By effectively defining two sparse matrix structures of dimensions `nisland x nv` and `nisland x nefc`, respectively, this representation is more conducive to reuse of existing sparse matrix utility functions, while being cache-friendlier by making sequential indices adjacent in memory.
