  Log Message:
  -----------
  [PowerPC] The builtins load8r and store8r are Power 7 plus.

This patch makes sure that the builtins __builtin_ppc_load8r and
__ builtin_ppc_store8r are only available for Power 7 and up.
Currently the builtins seem to produce incorrect code if used for
Power 6 or before.
