revset: drop pre-lazyset optimization for stringset of subset == entire repo

It was introduced at e44ebd2a142a, where spanset.__contains__() did not exist.
Nowadays, we have to pay huge penalty for len(subset).

The following example showed that OR operation could be O(n * m^2)
(n: len(repo), m: number of OR operators, m >= 2) probably because of
filteredset.__len__.

revset #0: 0|1|2|3|4|5|6|7|8|9
0) wall 8.092713 comb 8.090000 user 8.090000 sys 0.000000 (best of 3)
1) wall 0.445354 comb 0.450000 user 0.430000 sys 0.020000 (best of 22)
2) wall 0.000389 comb 0.000000 user 0.000000 sys 0.000000 (best of 7347)
(0: 3.2.4, 1: 3.1.2, 2: this patch)

test variable isolation, variable placeholders are rewritten as string
then parsed and matched again as string. Check they do not leak too
far away.
