Save space and reduce I/O time (reading and writing) by compressing the marshaled code in  files.

In my code tree for Python 3, there was a nice space savings 19M to 7M.  Here's some of the output from my test:

    8792 ->     4629 ./Tools/scripts/__pycache__/reindent.cpython-35.pyc
    1660 ->     1063 ./Tools/scripts/__pycache__/rgrep.cpython-35.pyc
    1995 ->     1129 ./Tools/scripts/__pycache__/run_tests.cpython-35.pyc
    1439 ->      973 ./Tools/scripts/__pycache__/serve.cpython-35.pyc
     727 ->      498 ./Tools/scripts/__pycache__/suff.cpython-35.pyc
    3240 ->     1808 ./Tools/scripts/__pycache__/svneol.cpython-35.pyc
   74866 ->    23611 ./Tools/scripts/__pycache__/texi2html.cpython-35.pyc
    5562 ->     2870 ./Tools/scripts/__pycache__/treesync.cpython-35.pyc
    1492 ->      970 ./Tools/scripts/__pycache__/untabify.cpython-35.pyc
    1414 ->      891 ./Tools/scripts/__pycache__/which.cpython-35.pyc
19627963 ->  6976410 Total

I haven't measured it yet, but I believe this will improve Python's start-up time (because fewer bytes get transferred from disk).
