encoding/csv: update and add CSV reading benchmarks

2016-10-05T04:29:07+00:00

Benchmarks broken off from https://golang.org/cl/24723 and modified to
allocate less in the places we're not trying to measure.

encoding/csv: Preallocate records slice

2015-04-26T16:28:51+00:00

Currently parseRecord will always start with a nil
slice and then resize the slice on append. For input
with a fixed number of fields per record we can preallocate
the slice to avoid having to resize the slice.

This change implements this optimization by using
FieldsPerRecord as capacity if it's > 0 and also adds a
benchmark to better show the differences.
