nit: I think we can use macros from the AST instead of manually writing
`"_TEST_MACRO"` and `"_TEST_H"`.
Something like this:
```cpp
auto AST = TU.build();
EXPECT_THAT(AST.getMacros().Names.keys(),
testing::UnorderedElementsAreArray(DefinedMacros));
```
We can assume that `AST.getMacros().Names` is correct, because we already have
tests in `PreambleTest.cpp` for this.
