AMDGPU: Fix multi-use shl/add combine
This was using a custom function that didn't handle the addressing modes properly for private. Use isLegalAddressingMode to avoid duplicating this. Additionally, skip the combine if there is only one use since the standard combine will handle it. llvm-svn: 318013
