This reverts commit 32e95a8.
* vectorize: optimize VectorSumCenter and HalfvecSumCenter The functions VectorSumCenter and HalfvecSumCenter were not being vectorized by the compiler. A few slight changes will allow these optimizations to take place and get a performance boost by utilizing SIMD instructions. This optimization helps improve performance of vector operations in IVF index building and updating. * Removing const, commenting that it is only vectoirzed on ARM
* 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

Postgres standard way to check for list emptiness is to compare a pointer to NIL rather than NULL.
