vector: benchmark the floating point code path.
Browse files Browse the repository at this point in the history 
Specifically, this commit adds Benchmark.*1024.* functions, and then
gofmt's some other Benchmark functions.

There are existing floating point benchmarks in acc_test.go, but they
have narrower scope. The benchmarks in vector_test.go are closer to
end-to-end benchmarks for the package.
