This adds actual test cases for all the cases that are listed in a code comment in the implementation of this function; having such test coverage eases doing further modifications to the function. This relands b4b35a5d2b4ee26bf79b8a92715dd200f3f9cc49. This time, the new test is excluded if building with dylibs or shared libraries enabled, as the clang::toolchains::Generic_GCC class is marked LLVM_LIBRARY_VISIBILITY, giving it hidden visibility in such builds, making it unreferencable outside of the dylib/shared library.
