Use pg_memory_is_all_zeros() in pgstatfuncs.c.
There are a few places in this file that use memset() and memcmp()
to determine whether a section of memory is all zeros. This commit
modifies them to use pg_memory_is_all_zeros() instead. These
aren't expected to be hot code paths, but this may optimize them a
bit. Plus, this allows us to remove some variables that were only
needed for the memset() and memcmp().
