Title: Improve generic CPU support in qcrs and add ARM NEON support

Also:
Don't assume SSSE3 on x86_64 (e.g. for AMD Opteron)
Allow vector instruction set to be overridden on command line (vectormode)
Only enable explicit vector intrinsics on GCC

Tested with Ubuntu 12.04/GCC 4.6 and Ubuntu 12.10/GCC 4.7 on Xeon (SSSE3), Opteron (SSE2), Calxeda (NEON), and without intrinsics (cmake -Dvectormode=none).
