SPIRV-Tools/test/TextWordGet.cpp
Lei Zhang 8bd75d650e Clean up CMake configuration and address compiler warnings.
- Removed dead configuration in CMakeLists.txt.
- Used target_compile_options() instead of CMAKE_{C|CXX}_FLAGS.
- Turned on warnings on tests.
- Fixed various warnings for comparing signed with unsigned values.
- Removed dead code exposed by compiler warnings.
