What's the progress on the Mobile Port?

[Johan Vos]

Hi Julian,

The main branch in the mobile repo [1]  has a rather small diff from the
head of the jdk [2]. With this diff, it is possible to build the native
class libs for iOS and Android.
I have a local version of hotspot (Zero) that allows to run HelloWorld on
iOS, as of yesterday. That requires lots of cleanup, and then I'll create a
PR.
I'll add a more complete status update soon (within the next few days),
always good to hear people want to read about it :)
