fileset: combine union of basic patterns into single matcher
This appears to improve query performance in a big repository than I thought.
Writing less Python in a hot loop, faster computation we gain.
$ hg files --cwd mozilla-central --time 'set:a* + b* + c* + d* + e*'
(orig) time: real 0.670 secs (user 0.640+0.000 sys 0.030+0.000)
(new) time: real 0.210 secs (user 0.180+0.000 sys 0.020+0.000)

fileset: reorder 'or' expression by weight
Yuya Nishihara <yuya@tcha.org> [Sat, 04 Aug 2018 17:08:33 +0900] rev 38902
fileset: introduce weight constants for readability
These constants are defined in the filesetlang module since it's the
bottommost module depending on WEIGHT_CHECK_FILENAME, and extensions
will be likely to import it to process function arguments.
Credit for the naming goes to Augie Fackler.
