+ Start to translate preprocessor's false conditional blocks too:
based on clang's https://reviews.llvm.org/D66597;
available only starting from LLVM 10.0 or trunk.
+ Option -skip-excluded-preprocessor-conditional-blocks for skipping excluded conditional blocks:
the default behavior for hipify-clang built with LLVM < 10.0;
false by default for hipify-clang built with LLVM 10 or trunk.
+ Add 4 preprocessor unit tests, 2 of which are LLVM 10.0 only
+ Update couple of existing tests by setting -skip-excluded-preprocessor-conditional-blocks option:
update lit testing accordingly
