Use gcc vector extensions for SIMD scrypt key derivation function
The code can be compiled for different architectures from the same
source starting with gcc 4.7. But SSE2/Altivec/SPU targets have
compatibility wrappers, which also allow the use of older versions
of gcc.
Two hashes are processed at the same time, so twice bigger scratch
buffer is needed (~256K vs. ~128K).
Speedup on Cell PPU (32-bit), single thread, 3.2GHz:
~0.58 khash/s -> ~1.79 khash/sec
