Populate list of vectorizable functions for Accelerate library.

Summary:
This patch adds majority of supported by Accelerate library functions to the
list of vectorizable functions.

The full list of available vector functions could be found here:
https://developer.apple.com/library/mac/documentation/Performance/Conceptual/vecLib/index.html

Test Plan: Unit tests are added.
