i965: Safely iterate the predecessors of the end block.
We want to insert code in each of the predecessors of the end block.
This code includes a nir_if, which would split the block, altering
the set. To avoid that, I emitted a dead constant at the end of each
block before splitting it, so that the set of predecessors remained
unchanged. This was admittedly ugly.
Connor suggested instead saving a copy of the set, so we can iterate
it safely. This is also a little ugly, but a much better plan.
