jdk 8 port: hotspot builds and runs

[Volker Simonis]

Hi Jonathan,

I've updated the jdk8 repositories yesterday to fix the build on
Windows/Linux x86 first. This was necessary because of the change which
introduced the new Date and Time API the jdk8 couldn't bootstrap itself
anymore which broke our nightly builds. This problem was however fixed with
a recent change. After I got that change, I also had to sync the new
nashorn repository which is now part of the default build. With these
changes we now have at least a running build on the Oracle platforms.

I will integrate the new JSR292 implementation into our jdk7u repository
today and then try to get the new jdk8 build up and running on Linux/PPC
and AIX (in that order:)

Goetz only build the new HotSpot from jdk8 and tested it with our jdk7 JDK.
We don't have tired compilation on PPC and that's probably not detected by
the new build that's why you get the problems mentioned below. As I said,
I'll have a look at it...

Regards,
Volker
