Limit depth of forced recursion for CLOBBER_CACHE_RECURSIVELY.
It's somewhat surprising that we got away with this before. (Actually, since nobody tests this routinely AFAIK, it might've been broken for awhile. But it's definitely broken in the wake of commit f868a8143.) It seems sufficient to limit the forced recursion to a small number of levels. Back-patch to all supported branches, like the preceding patch. Discussion: https://postgr.es/m/12259.1532117714@sss.pgh.pa.us
