Alexander Timofeev 37bd9bd137 [AMDGPU] Partial revert for the ba447bae74
"Divergence driven ISel. Assign register class for cross block values
       according to the divergence."
       that discovered the design flaw leading to several issues that
       required to be solved before.

       This change reverts AMDGPU specific changes and keeps common part
       unaffected.
