Suggested patch

There's fixed version of the patch:

1) If I see correctly, there was error in: struct cgraph_edge *nexte =
e->next_callee
2) We should not remove alias if there's a thunk that wasn't redirected
3) gcc_assert must be changed for these cases

Patch can run the testcase and survives FF with -O3 and -flto. Regression tests
have been running.
