Enabled Partial Linkage may replace entire IR expressions with a stub
during klib linking and loading. This may break the incremental cache
dependency graph. Dropping incremental cache files after updating klibs
(e.g. update klib version) covers almost all cases which
could not be tracked due to a broken dependency graph.
This patch could be reverted after fixing KT-57347
