[analyzer] Handle another Android assert function.

Authored by ygribov on Dec 29 2015, 7:51 AM.



Android's assert can call both assert and assert2 functions under the cover but NoReturn does not handle the latter. This patch fixes this.

Relevant snippet from bionic/libc/include/assert.h:

# if __ISO_C_VISIBLE >= 1999
#  define       assert(e)       ((e) ? (void)0 : __assert2(__FILE__, __LINE__, __func__, #e))
__dead void __assert2(const char *, int, const char *, const char *);

Thanks Yuri! This looks great. Can you also add a test to tests/analysis/NoReturn.m for this? You can follow the example of test_wassert there.
