The patch is straighforward:
- The sparc32 v8 implementations are moved as the generic ones.
- A configure test is added to check for either __sparc_v8__ or
__sparc_v9__.
- The triple names are simplified and sparc implies sparcv8.
The idea is to keep support on sparcv8 architectures that does support
CAS instructions, such as LEON3/LEON4.
Checked on a sparcv9-linux-gnu and sparc64-linux-gnu.
