The test for issue 8945 was marked to only run on gccgo, but there was no reason for that. It broke for gccgo using GCC 10, because GCC 10 defaults to -fno-common. Make the test run on gc, and split it into test.go and testx.go to make it work with GCC 10. The test for issue 9026 used two identical structs which GCC 10 turns into the same type. The point of the test is not that the structs are identical, but that they are handled in a particular order. So make them different.
