Revert "Add a perf test for #26425"

This test has a large memory spike currently, which makes the test
sensitive, since if you allocate a little more or less, the precise
location where GC happens shifts and you observe a different part of the
spike.

Andreas told me to revert the patch for now, and he will add it back
when he fixes the memory spike.

This reverts commit 41bdb16fd083110a06507248f648c507a2feb4af.
