or Octave": https://octave.discourse.group/t/wip-stack-vm-for-octave/2884/10

Add checkelement_value to Array to be able to get an element value
without calling make_unique, like const T& operator[](size_t idx),
but this works with non-const Array:s.

Also inline index computations. Benifitial for operator look-up.

Adding branch hint macros OCTAVE_LIKELY and OCTAVE_UNLIKELY,
using __builtin_expect for gcc and clang.
