icedtea6 1.11 branching on 2012-01-06

[Chris Phillips]

Hi Omair

I think its pretty badly broken all across the board,
I've never gotten -XComp to work reliably with shark/llvm
with any combination of llvm / hs. HS20+ is definitely broken
in several ways.

After we get zero / jsr 292 functional,
then maybe LLVM's new interfaces will have stabilized and it can be fixed.
