Pop intersected postings heap without popping ( #10092 )
...
See this comment for detailed explanation:
https://github.com/prometheus/prometheus/pull/9907#issuecomment-1002189932
TL;DR: if we don't call Pop() on the heap implementation, we don't need
to return our param as an `interface{}` so we save an allocation.
This would be popped for every label value, so it can be thousands of
saved allocations here (see benchmarks).

Label values with matchers by intersecting postings ( #9907 )
...
* LabelValues w/matchers by intersecting postings
Instead of iterating all matched series to find the values, this
checks if each one of the label values is present in the matched series
(postings).
Pending to be benchmarked.

* Don't expand postings to intersect them
Using a min heap we can check whether matched postings intersect with
each one of the label values postings. This avoid expanding postings
(and thus having all of them in memory at any point).
Slightly slower than the expanding postings version for some cases, but
definitely pays the price once the cardinality grows.
Still offers 10x latency improvement where previous latencies were
reaching 1s.

TSDB: demistify SeriesRefs and ChunkRefs ( #9536 )
...
* TSDB: demistify seriesRefs and ChunkRefs
The TSDB package contains many types of series and chunk references,
all shrouded in uint types. Often the same uint value may
actually mean one of different types, in non-obvious ways.
This PR aims to clarify the code and help navigating to relevant docs,
usage, etc much quicker.
Concretely:
* Use appropriately named types and document their semantics and
relations.
* Make multiplexing and demuxing of types explicit
(on the boundaries between concrete implementations and generic
interfaces).
* Casting between different types should be free. None of the changes
should have any impact on how the code runs.

Speed up BenchmarkPostings_Stats ( #9213 )
...
The previous code re-used series IDs 1-1000 many times over, so a lot
of time was spent ensuring the lists of series were in ascending order.
The intended use of `MemPostings.Add()` is that all series IDs are
unique, and changing the benchmark to do this lets it finish ten times
faster.
(It doesn't affect the benchmark result, just the setup code)
