R600/SI: Add basic support for more integer vector types.
v1i32, v2i32, v8i32 and v16i32. Only add VGPR register classes for integer vector types, to avoid attempts copying from VGPR to SGPR registers, which is not possible. Patch By: Michel Dänzer Signed-off-by: Michel Dänzer <michel.daenzer@amd.com> Reviewed-by: Tom Stellard <thomas.stellard@amd.com> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174632 91177308-0d34-0410-b5e6-96231b3b80d8
