  Log Message:
  -----------
  AMDGPU/GlobalISel: Don't select boolean phi by default

This is currently missing most of the hard parts to lower correctly,
so disable it for now. This fixes at least one OpenCL conformance test
and allows it to pass with fallback. Hide this behind an option for
now.
