Vectorizing vector_concat for improved performance ( #861 )
...
* Vectorizing vector_concat for improved performance
On an ARM chip this should generate SIMD instructions to copy the two
incoming vectors to the new vector as opposed to doing it all in
software.
* Moving declarations to above CheckDim
* Removing const from dims
* Formatting

Fix integer overflow in subvector() function ( #530 )
...
`end = start + count` can overflow if `start` is very large. That
leads to a segfault later in the function. Add test case for it.
