SIMD: add VECTOR_ELEMENT macro

Browse Source 
Useful in cirumstances where you want to work with individual elements
of a vector, typically after you've done some vector-compatible operations
(mass-hashing, for example) but now need to do some non-vector-friendly
work (like executing most decryption algorithms).
