R600: Try to use lower types for 64bit division if possible v2: add and enable tests for SI Signed-off-by: Jan Vesely <jan.vesely@rutgers.edu> Reviewed-by: Matt Arsenault <Matthew.Arsenault@amd.com> llvm-svn: 226881

AMDGPU: Cleanup and generate 64-bit div tests Split out r600 tests, and try to be more consistent with coverage. Cover a few more cases for 24-bit optimization and constants.
