Alexey Samsonov e29c6731aa [Sanitizer/ASan] Simplify the code that prints and symbolizes stack traces. Fall back to module+offset if user-provided symbolizer failed. Use weak function __asan_symbolize instead of __asan_set_symbolize_callback in ASan interface, so that we're able to symbolize reports for errors that happen before the main() is called, for example, during module initialization.

Chandler Carruth b156b56a28 Revert r163411 based on review discussion.
In code review, it looked like these warnings do not actually fire with
modern Clang or GCC. However, the pragma is flat out rejected by GCC in
many configurations (-Werror) so it ended up causing more problems than
it fixed.

Daniel agreed with reverting this, but I think didn't have time to get
to it.
