Since `seps` is a variable, `seps[0]` has to be bounds-checked every
time. Replacing with a constant everywhere it is used skips this
overhead.

labels: optimize String method (#13673)
Use a stack buffer to reduce memory allocations.

`Write(AppendQuote(AvailableBuffer` does not allocate or copy when
the buffer has sufficient space.

Also add a benchmark, with some refactoring.

Prevent adding back golang.org/x/exp/slices.

Bryan Boreham a3e02f35d6 labels: extract common code between slice and stringlabels
This reduces bulk and should avoid issues if a fix is made in one file
and not the other.

A few methods now call `Range()` instead of `range`, but nothing
performance-sensitive.
