[NFC][OpenMP] Add tests for mapping pointers and their dereferences. (#146934) 
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).
