Summary: Many of our tests need to initialize certain subsystems/plugins of LLDB such as `FileSystem` or `HostInfo` by calling their static `Initialize` functions before the test starts and then calling `::Terminate` after the test is done (in reverse order). This adds a lot of error-prone boilerplate code to our testing code. This patch adds a RAII called SubsystemRAII that ensures that we always call ::Initialize and then call ::Terminate after the test is done (and that the Terminate calls are always in the reverse order of the ::Initialize calls). It also gets rid of all of the boilerplate that we had for these calls. Per-fixture initialization is still not very nice with this approach as it would require some kind of static unique_ptr that gets manually assigned/reseted from the gtest SetUpTestCase/TearDownTestCase functions. Because of that I changed all per-fixture setup to now do per-test setup which can be done by just having the SubsystemRAII as a member of the test fixture. This change doesn't influence our normal test runtime as LIT anyway runs each test case separately (and the Initialize/Terminate calls are anyway not very expensive). It will however make running all tests in a single executable slightly slower.
