[PATCH] D87556: [amdgpu] Lower SGPR-to-VGPR copy in the final phase of ISel.

hliao added a comment.

With this patch, we reduce the register pressure for certain tests which could be improved up to 10%. As the code generated would be visibly different from the previous one, regression tests are updated as well.
