"[PATCH] eal: define generic vector types" [1][2]

Using built-in vector types forces compilers to consider SIMD instructions in
specific places in order to improve performance on both IBM POWER8 and Intel
architectures.

For example, testpmd single-thread I/O forwarding packets per second
performance is improved by 6% on Intel platforms.
