  AMDGPU/GlobalISel: Account for G_PHI result bank

Sometimes the result bank of the phi is already assigned to something,
and should not be ignored. This is in preparation for additional
boolean phi handling changes.

Also refine the logic to fix some cases that were incorrectly deciding
to use SGPRs.

  AMDGPU: Improve llvm.round.f64 lowering for CI+

The path already used for f16/f32 works a lot better when v_trunc_f64
is available.
