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.

* 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

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
new keywords: `start` and `end`. In grouping options and in metric
names, these keywords took precedence over metric or label names, so
that those metrics and labels could no longer be referenced.
