Original r297566 is splitted into two parts. This is part one, which adds "RUN" command for test cases. Unit/arm/call_apsr.S is updated to support thumb1. It also fixes a bug in arm/aeabi_uldivmod_test.c gcc_personality_test is XFAILED as the framework cannot handle it so far. cpu_model_test is also XFAILED for now as it is expected to return non-zero. TODO: A few tests are XFAILed for armhf and aarch64. We need further investigating. [1,2] Tracks the issue.
