Eric Anholt 09beee378c Don't do GTT maps on objects bigger than half the available aperture size. 
The basic problem is that software fallbacks will do single instructions that
copy from one GTT-mapped BO into another GTT-mapped BO.  If we can't get both
of them bound simultanously, we fault one in, retry the instruction, fault the
other in (kicking out #1), retry the instruction, fault #1 back in
(kicking out #2), etc.

Note that we'll still get into a nasty spot if you do a composite operation
with a mask where all 3 are big-but-less-than-half-available-aperture, where
you'll thrash.  It at least means you'll make progress, though, since each
instruction will only be operating on two BOs at at time, and the situation
seems unlikely.
