[PATCH] D52221: require lower-switch in preISel passes for AMDGPU

Good to hear the new DA can handle this. We need lowered switches for the control flow lowering anyway, though, so we may as well do it this way.

The test case is extremely mysterious to me, though. What is it that's actually being tested here? From the description I understand it's the divergence of the phi in sw.epilog? I don't see how that relates to the CHECK lines.
