* Tests for Mempostings.{Add,Get} data race
* Fix MemPostings.{Add,Get} data race
We can't modify the postings list that are held in MemPostings as they
might already be in use by some readers.
* Modify BenchmarkHeadStripeSeriesCreate to have common labels
If there are no common labels on the series, we don't excercise the
ordering part of MemSeries, as we're just creating slices of one element
for each label value.
