fileset: optimize 'x and not y' to 'x - y'
'x - y' is first rewritten to 'x and not y' so that x and y are reordered
by weight.

fileset: reorder 'and' expression to evaluate basic patterns first
Timing of a crafted example (when disk cache is warm):
$ hg files set:'binary() and path:contrib'
(orig) time: real 0.140 secs (user 0.120+0.000 sys 0.020+0.000)
(new) time: real 0.040 secs (user 0.030+0.000 sys 0.010+0.000)

fileset: roughly adjust weights of functions
... in order to move status predicates far away from basic patterns. I don't
know if each weight is appropriate, but it should be good enough as a start.
Yuya Nishihara <yuya@tcha.org> [Sat, 21 Jul 2018 15:52:26 +0900] rev 38869
fileset: add stub for weight-based optimization
The main purpose of this change is to group basic patterns, which can be
mapped to a plain matcher. I'm not so interested in a weight of each function.
Yuya Nishihara <yuya@tcha.org> [Sat, 21 Jul 2018 16:16:44 +0900] rev 38868
fileset: reject 'negate' node early while transforming parsed tree
That's how a 'negate' node is processed in revset.
Yuya Nishihara <yuya@tcha.org> [Sat, 21 Jul 2018 16:13:30 +0900] rev 38867
fileset: drop 'group' node from tree to be evaluated
This helps rewriting a parsed tree.
Yuya Nishihara <yuya@tcha.org> [Sat, 21 Jul 2018 16:11:36 +0900] rev 38866
fileset: add phase to transform parsed tree
This isn't strictly necessary, but I decided to just follow the strategy
of the revset parsing.
