While implementing a different feature, I found that Labels.Get() was
performing a linear search. I wondered whether it would perform any
better with a binary search approach, and wrote a benchmark: the answer
is that it's probably doesn't worth it, so I just decided to leave the
benchmark and the results for the next reader.

* Avoid deadlock when processing duplicate series record
`processWALSamples()` needs to be able to send on its output channel
before it can read the input channel, so reads to allow this in case the
output channel is full.

* Use global string map for MatchType.String()
We were unnecessarily creating a new map for each call of String().
This is a 10x improvement in MatchType.String() performance in time,
from 53ns to 4ns on my i7 laptop, and I guess that this method is being
called quite often so why throw out the resources.
I was surprised that benchmark says that there are no allocations made
in the old version.
I also tries using `//go:generate stringer` and the result is even
better, at about 2.8ns, but having to keep the generated code updated
isn't worth the change (at least it's bigger than a small change I was
intended to do)
Benchmark comparison:
name \ time/op old global_map stringer
MatchType_String 53.6ns ± 1% 4.1ns ± 1% 2.8ns ± 1%

* Use array instead of map
Since MatchType is an iota type, we can safely use an array here.
This solution is even better:
name \ time/op old global_map stringer array
MatchType_String 53.6ns ± 1% 4.1ns ± 1% 2.8ns ± 1% 1.0ns ± 1%
name \ alloc/op old global_map stringer array
MatchType_String 0.00B 0.00B 0.00B 0.00B
name \ allocs/op old global_map stringer array
MatchType_String 0.00 0.00 0.00 0.00

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)

* PromQL: Fix start and end keywords masking label and metric names
This commit fixes an issue with the "at modifier" that introduced two

names, these keywords took precedence over metric or label names, so
that those metrics and labels could no longer be referenced.
