match: match explicit file using a set
The matcher as all the logic to do quick comparison against explicit patterns,
however the pattern matcher was shadowing the code using that set and used the
compiled regex pattern in all cases, which is quite slow. We restore the usage
of the set based matching to boost performance.
Building the regexp is still consuming a large amount of time (actually, the
majority of the time), which is still silly. Maybe using re2 would help that,
but this is a quest for another adventure.
Another path to improve this is to have a pattern type dedicated to match the
exact path to a file only (not a directory). This pattern could use the set
matching only and be skipped in the regex all together.
Benchmarks
==========
In the following benchmark we are comparing the `hg cat` and `hg files` run
time when matching against all files in the repository. They are
run:
- without the rust extensions
- with the standard python engine (so without re2)
Performance improvement in this series
