kcc added inline comments.

Comment at: 
compiler-rt/test/sanitizer_common/TestCases/sanitizer_coverage_control_flow.cpp:1
+// Tests -fsanitize-coverage=control-flow.
+
----------------
I suggest to make this test smaller:
* foo() can by empty (but avoid inlining)
* main() can have a single conditional call to foo

* main should also have a single conditional indirect call to test the -1 indir 
call marker. 

* __sanitizer_cov_cfs_init should capture its arguments and return

* main should insepct the arguments captured in __sanitizer_cov_cfs_init and 
verify that it sees main() and foo(), and that main contains calls to foo() and 
indir function, outside of the entry BB.
