revset: make use of natively-computed set for 'draft()' and 'secret()'
If the computation of a set for each phase (done in C) is available,
we use it directly instead of applying a simple filter. This give a
massive speed-up in the vast majority of cases.
On my mercurial repo with about 15000 out of 40000 draft changesets:
revset: draft()
plain min first last
0) 0.011201 0.019950 0.009844 0.000074
1) 0.000284 2% 0.000312 1% 0.000314 3% 0.000315 x4.3
Bad performance for "last" come from the handling of the 15000 elements set
(memory allocation, filtering hidden changesets (99% of it) etc. compared to
applying the filter only on a handfuld of revisions (the first draft changesets
being close of tip).
This is not seen as an issue since:
* Timing is still pretty good and in line with all the other one,
* Current user of Vanilla Mercurial will not have 1/3 of their repo draft,
This bad effect disappears when phase's set is smaller. (about 200 secrets):
revset: secret()
plain min first last
0) 0.011181 0.022228 0.010851 0.000452
1) 0.000058 0% 0.000084 0% 0.000087 0% 0.000087 19%
