OK, I fixed this as Michael suggested by installing the 64 bit python3 
(it's a pity that python.org didn't offer that to me as a download on 
their front page - that's a bit ugly).

However, when it came to running these tests that was a miserable 
failure. And indeed, we don't run any regression tests for plpython3 on 
MSVC.

So I committed this with just python2 tests enabled. All the buildfarm 
MSVC hosts seem to be using python2 anyway.

Meanwhile, we have some work to do on the mingw/gcc side.

These changes help make some progress - they let compilation succeed for 
hstore_plperl but I still get linkage failures. I suspect we need some 
things marked for export that we haven't to be marked needed before.
