AMDGPU/GlobalISel: Tolerate negated control flow intrinsic outputs

If the condition output is negated, swap the branch targets. This is
similar to what SelectionDAG does for when SelectionDAGBuilder
decides to invert the condition and swap the branches.

This is leaving behind a dead constant def for some reason.

AMDGPU/GlobalISel: Custom lower control flow intrinsics

Replace the brcond for the 2 cases that act as branches. For now
follow how the current system works, although I think we can
eventually get rid of the pseudos.
