cpython-lru_cache-weakref: Python/bltinmodule.c annotate

annotate Python/bltinmodule.c @ 31343:0c1d2062dee3 legacy-trunk

Apply map/zip pre-sizing optimization to a broader class of objects. Formerly, the length was only fetched from sequence objects. Now, any object that reports its length can benefit from pre-sizing.
