The output of the compile-and-run tests is incorrect. These will be used for reference in future commits that resolve the issues. Also updated the existing clang LIT test, target_map_both_pointer_pointee_codegen.cpp, with more constructs and fewer CHECKs (through more update_cc_test_checks filters).
