Add back Windows CI, we lost it when tsdb was merged into the prometheus
repo. There's many tests failing outside tsdb, so only test tsdb for
now.

* Cleanup PromQL functions
The engine ensures, for Matrix functions, that functions are called with exactly one series at the time.
Therefore a lot of code can be inlined and we can directly assume the first element of the arguments exists and contains all the samples needed.

strings.Compare isn't meant to be used, and this way we save one
comparison which is thus very slightly cheaper.

This function is only used in one place to format an error message when
encountering multiple matches on the "one" side of a
one-to-many/many-to-one vector match, which is probably why nobodoy has
noticed this before. The hashing is already done correctly and excludes
the metric name label when using the "ignoring" matching modifier.

The parser benchmarks called the `ParseMetric` function instead of the `ParseExpr` function, which resulted in parsing failing every time.
This means only the case of PromQL parser failure was benchmarked.

* Add parser method to produce errors messages about unexpected items
* PromQL: use parser.unexpected in generated parser

Also improves TestPopulateLabels: testutil.ErrorEqual just returned a
bool without failing the test.

Rather than buffer up symbols in RAM, do it one by one
during compaction. Then use the reader's symbol handling
for symbol lookups during the rest of the index write.
There is some slowdown in compaction, due to having to look through a file
rather than a hash lookup. This is noise to the overall cost of compacting
series with thousands of samples though.
