jdk 8 building just jdk

I whole heartedly disagree. I've said it before and I say it again.
I do not want to build hotspot or anything else besides JDK
I do not want to maintain all the disk space for these.
The overhead of these repos is painful.
It is not fragile to build only JDK. I have > 10 years of experience here.

I used to do incrementals in 10-15 seconds with the old build. Much 
better than 3 mins.
I tried JDK_FILTER but it was not reliable. sjavac working by default 
was supposed to
be a pre-requisite to the new build but that didn't happen.

I've learned the new build is fast on Linux but slow on Windows which is 
what matters most.

Bear in mind that 999/1000 of my builds are incremental and calculate 
how that adds up.

Bottom line: the new build is costing me a lot. If people who don't work 
primarily on
Windows aren't working on this, then that needs to be fixed.
