Weiming Zhao 9b7bbeca48 [Builtin] Implement lit-test support (part 1 of 2: test cases update) 
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.
