Hi Nico,

I'm not gonna TBR this, or land it right now (the tree is a bit scary looking),
but hopefully this should be ok; Daniel's logic for r1896 being the problem
looks like a sufficiently strong hypothesis that I think we'll be okay here now
that it's reverted. The iOS build is still technically broken due to the command
cache, but that was already the case; the roll shouldn't make it worse :/

If you think we're in a reasonable state I'll land this when the tree is
greener.

Doh, of course LKGR hasn't caught up to the revert yet so the patch doesn't
apply. I'll.. wait.
