The breakage was introduced in af12322e9d.
__has_builtin was introduced to GCC in version 10, and the arithmetic overflow builtins were available since version 5.
Fixesdeepmind/mujoco#386.
Tested with GCC 9.

mj_makeModel returns NULL if any of the array sizes are negative. Callers of the function need to handle that case.

The introduction of additional mjData arrays for the implicit integrator caused in a shift in data alignment in memory. In certain combinations of machines and models, this change resulted in ~5% performance regression that appears to be attributable to L2 cache misses.
This change aligns all arrays in mjData to the boundary of a typical L2 cache line size. Benchmarking shows that this resolves the performance regression on a Broadwell machine.

Indiscriminate memset into d->buffer and m->buffer previously caused msan to not detect uninitialized reads.
Also fix tests with uninitialized read bugs that are detected by msan after this change.
