[RFC] merge in the libobjc branch

[Andrew Pinski <pinskia at physics dot uc dot edu>]

I will commit this merge from the libobjc branch on Sunday if
there are no objections.  The patch is self contained in
libobjc so there should be no issues about can I do this.

Then I will merge from the mainline into the libobjc branch.

Thanks,
Andrew Pinski
