Matthijs Kooijman b7e103ba41 Fix some llvm-gcc warnings in testcases, mostly by adding includes or adding
declarations. These are the fixes that I was pretty confident about, there are
still a lot of other llvm-gcc warnings of which I'm not sure if they can be
safely ignored or fixed, without breaking the test case.

This fixes 11 testcases.
