Stop combining loads and stores with PPCISD::ADD_TLS before we can merge the
node with with TLS_LOCAL_EXEC_MAT_ADDR. The issue is that
TLS_LOCAL_EXEC_MAT_ADDR cannot be selected by itself and requires the previous
ADD_TLS node that goes with it. However, we sometimes try to combine ADD_TLS
with loads and stores that come after it. If this happens then the ADD_TLS is
removed and TLS_LOCAL_EXEC_MAT_ADDR cannot be selected.
While this bug fix will address the issue it my not be ideal from a performance
perspective as we may be able to add patterns to combine TLS_LOCAL_EXEC_MAT_ADDR
with ADD_TLS with the load and store that comes after it all in one. However,
this is beyond the scope of this patch.
