* Fix panic in ARM builds of Prometheus (#6110)
An extra sync.Pool was added during a refactor which caused some 64 bit,
atomically accessed variables to no longer be 64 bit aligned. By moving
all atomically accessed variables to the beginning of the struct they
are guaranteed to be 64 bit aligned.

LiveReaders are instantiated `number of remote write queues * segments`
times, which would cause double registration of the metrics. Instead
this should be orchestrated by the layer above, instantiating the live
reader.

* refactor block size calculation
The block size is kept in memory and not in the meta file anymore.
It now includes the size of the meta file itself for a more
correct block size.
It fixes a bug where the size didn't change when calling `block.Delete()`.
Adds a dedicated test to ensure correct block sizes.
This allows opening a db in a read only mode as it doesn't write to the meta file anymore.

reduce disk usage by half while incurring a negligible CPU cost.

* Add unittests for PostingsForMatcher.
* Selector methods are all stateless, don't need a reference.
* Be smarter in how we look at matchers.
Look at all matchers to see if a label can be empty.
Optimise Not handling, so i!="2" is a simple lookup
rather than an inverse postings list.
All all the Withouts together, rather than
having to subtract each from all postings.
Change the pre-expand the postings logic to always do it before doing a
Without only. Don't do that if it's already a list.
The initial goal here was that the oft-seen pattern
i=~"something.+",i!="foo",i!="bar" becomes more efficient.
