Alexey Samsonov 51ae983718 [Sanitizer]: Introduce a common internal printf function.

Alexey Samsonov 6f596767c3 Stub files for common symbolizer for AddressSanitizer and ThreadSanitizer tools. 
It is an analogue of addr2line utility and should allow to map instruction address to a location
in source code at run-time. It should use debug information (in DWARF) in a binary, and hopefully
it would be possible to re-use code from llvm/DebugInfo/DIContext.h

Bill Wendling 65adec933d Simplify the logic that tries to open the GCDA file at all costs. Basically, if 
we can't open the file even after creating all of the directories to it, then
just give up.

Bill Wendling bba2a7d46d * A bit of cleanup of the 'recursive_mkdir'. No functionality change. 
* Check for absolute paths before using the GCOV_PREFIX.
* Don't add an ending path separator if there's already one.

Alexander Potapenko 442002568c Introduce the check_malloc_usable_size flag (on by default). 
When the flag is set to zero, we do not check for errors in malloc_usable_size.

Dmitry Vyukov 7fb7330469 asan/tsan: weak interceptors 
The idea isthat asan/tsan can survive if user intercepts the same functions. At the same time user has an ability to call back into asan/tsan runtime. See the following tests for examples:
asan/output_tests/interception_failure_test-linux.cc
asan/output_tests/interception_test-linux.cc
asan/output_tests/interception_malloc_test-linux.cc
