64-bit Mac OS X: build and run without patches on mozilla-central

[Josh Aas]

We can now make 64-bit Mac OS X builds without any patches on mozilla-
central. The port is pretty stable already though there are no real
plugins available for it. x86-64 is actually the default architecture
if you're building mozilla-central on Mac OS X 10.6. Setting up a
tinderbox is bug 519060.

Here are some perf numbers from early October 2009:

We have not yet made any decisions about changing which architectures
we ship and officially support for Mac OS X.

I went ahead and updated the following MDC page:

Feel free to improve the documentation if needed.

Not even the java plugin right ?

I thought there had been a decision to try to get it in for 3.7.
