revset: optimize "x & fullreposet" case
If self is a smartset and other is a fullreposet, nothing should be necessary.
A small win for trivial query in mozilla-central repo:
revset #0: (0:100000)
0) wall 0.017211 comb 0.020000 user 0.020000 sys 0.000000 (best of 163)
1) wall 0.001324 comb 0.000000 user 0.000000 sys 0.000000 (best of 2160)
