    zlib: use more memory for a small deflate speedup.
    
    The LIT_MEM option uses slightly more memory (for base gzip(1),
    about 16kiB; according to the author, about 6% for default deflate
    settings) for a small speedup.
    
    The performance gain is more noticeable for input data with higher
    entropy and less significant for data that is highly compressible,
    such as source code and logs.
    
    (cherry picked from commit aea57ebcb1b053370ea1f0e29cdc666291bc5d5e)
