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.

==================================== Testing head checking code: Case C-2 ==================================== Mercurial checks for the introduction of new heads on push. Evolution comes into play to detect if existing branches on the server are being replaced by some of the new one we push. This case is part of a series of tests checking this behavior. Category C: checking case were the branch is only partially obsoleted. TestCase 1: 2 changeset branch, only the head is rewritten .. old-state: .. .. * 2 changeset branch .. .. new-state: .. .. * 1 new changesets branches superceeding only the head of the old one .. * base of the old branch is still alive .. .. expected-result: .. .. * push denied .. .. graph-summary: .. ..
