util: make nogc effective for CPython
279cd80059d4 made `util.nogc` a no-op. It was to optimize PyPy. But it slows
down CPython if many objects (like 300k+) are created.
For example, running `hg log -r .` without extensions in `hg-committed` with
14k+ obsmarkers have the following times:
before | after
hg | chg | hg | chg
-----------------------------
1.262 | 0.860 | 1.077 | 0.619 (seconds, best of 20 runs)
Therefore let's re-enable nogc for CPython.
