tags-cache: skip the filternode step if we are not going to use it When warming the hgtagsfnodescache, we don't need the actual result, so we can simply skip the part that "filter" fnode we read from the cache. So provide a quite visible speed up to the top level `hg debugupdatecache` function. ### data-env-vars.name = mozilla-try-2023-03-22-zstd-sparse-revlog # benchmark.name = hg.debug.debug-update-cache # bin-env-vars.hg.flavor = default # bin-env-vars.hg.py-re2-module = default # benchmark.variants.pre-state = warm before: 19.947581 after: 18.916804 (-5.17%, -1.03)
