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.

R600: optimize the UDIVREM 64 algorithm This is a squash of several optimization commits: - calculate DIV_Lo and DIV_Hi separately - use BFE_U32 if we are operating on 32bit values - use precomputed constants instead of shifting in UDVIREM - skip the first 32 iterations of udivrem v2: Check whether BFE is supported before using it Patch by: Jan Vesely Signed-off-by: Jan Vesely <jan.vesely@rutgers.edu> Reviewed-by: Tom Stellard <thomas.stellard@amd.com> llvm-svn: 207589
