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.

test sparse

  $ hg init myrepo
  $ cd myrepo
  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > sparse=
  > purge=
  > strip=
  > rebase=
  > EOF

  $ echo a > index.html
  $ echo x > data.py
  $ echo z > readme.txt
  $ cat > base.sparse <<EOF
  > [include]
  > *.sparse
  > EOF
  $ hg ci -Aqm 'initial'
  $ cat > webpage.sparse <<EOF
  > %include base.sparse
  > [include]
  > *.html
  > EOF
  $ hg ci -Aqm 'initial'

Clear rules when there are includes

  $ hg debugsparse --include *.py
  $ ls
  data.py
  $ hg debugsparse --clear-rules
  $ ls
  base.sparse
  data.py
  index.html
  readme.txt
  webpage.sparse

Clear rules when there are excludes

  $ hg debugsparse --exclude *.sparse
  $ ls
  data.py
  index.html
  readme.txt
  $ hg debugsparse --clear-rules
  $ ls
  base.sparse
  data.py
  index.html
  readme.txt
  webpage.sparse

Clearing rules should not alter profiles

  $ hg debugsparse --enable-profile webpage.sparse
  $ ls
  base.sparse
  index.html
  webpage.sparse
  $ hg debugsparse --include *.py
  $ ls
  base.sparse
  data.py
  index.html
  webpage.sparse
  $ hg debugsparse --clear-rules
  $ ls
  base.sparse
  index.html
  webpage.sparse
