Added safety checks to Array::xelem
There's no reason to have a method which never checks invariants, ever. Added
debugging checks to Array::xelem to help catch and debug out-of-bounds errors
and reference overlap
* configure.ac: Added configuration option for uniqueness-checking with xelem
* jit-typeinfo.cc (octave_jit_paren_scalar): Call const Array::xelem rather
than Array::xelem
* Array-util.h, Array-util.cc (check_out_of_range): Extract common pattern to
method
(check_index): Methods to check index is in-bounds
(compute_index): Added bool parameter check. does not check bounds when check
is false and BOUNDS_CHECKING is off
* Array.h, Array.cc (xelem): Use methods from Array-util.h to compute indices
(is_unique): Check if this is the only reference to data
* CmplxQR.cc, dbleQR.cc, fCmplxQR.cc, floatQR.cc
(form): Move second assignment to after the call to xelem
* lo-array-gripes.h, lo-array-gripes.cc (gripe_modifying_nonunique): Added
error message for when non-const xelem is called on non-unique array
