revset: fix order of nested 'or' expression (BC)
This fixes the order of 'x & (y + z)' where 'y' and 'z' are not trivial.
The follow-order 'or' operation is slower than the ordered operation if
an input set is large:
#0 #1 #2 #3
0) 0.002968 0.002980 0.002982 0.073042
1) 0.004513 0.004485 0.012029 0.075261
#0: 0:4000 & (0:1099 + 1000:2099 + 2000:3099)
#1: 4000:0 & (0:1099 + 1000:2099 + 2000:3099)
#2: 10000:0 & (0:1099 + 1000:2099 + 2000:3099)
#3: file("path:hg") & (0:1099 + 1000:2099 + 2000:3099)
I've tried another implementation, but which appeared to be slower than
this version.
ss = [getset(repo, fullreposet(repo), x) for x in xs]
return subset.filter(lambda r: any(r in s for s in ss), cache=False)
Create repo with old manifest

$ hg commit -m initial
We're using v1, so no manifestv2 entry is in requires yet.
$ grep manifestv2 .hg/requires

Let's clone this with manifestv2 enabled to switch to the new format for
future commits.
$ cd ..
$ hg clone --pull existing new --config experimental.manifestv2=1

$ echo newfootext > foo
$ hg commit -m new
Check that the manifest actually switched to v2.

Check that manifestv2 is used if the requirement is present, even if it's
disabled in the config.

Check that we can still read v1 manifests.
$ hg files -r 0

Check that entry is added to .hg/requires on repo creation
$ hg --config experimental.manifestv2=True init repo

Set up simple repo
$ echo a > file1

Check that 'hg verify', which uses manifest.readdelta(), works
