Something went wrong with the transfer to this repository, and all the assembly files wrt Float32 operations failed to pass the tests. Figure out what's wrong and fix it.

Added benchmarks. This fixes part 1 of issue #1

On a Core-i7 2600K at stock (unoverclocked speed) for float32:

$ go test -tags=avx -bench=.
BenchmarkVecAdd-8              	200000000	         9.06 ns/op
BenchmarkVanillaVecAdd-8       	30000000	        49.8 ns/op
BenchmarkVecSub-8              	200000000	         9.13 ns/op
BenchmarkVanillaVecSub-8       	50000000	        38.6 ns/op
BenchmarkVecMul-8              	200000000	         9.04 ns/op
BenchmarkVanillaVecMul-8       	30000000	        46.6 ns/op

tf32 and tf64 are at feature parity wrt to assembly functions. Still a bunch of fastmath stuff not ported over.
