Alexey Samsonov 38b1ec4317 [ASan] Add a default constructor for DWARFSection to initialize it with zeros.

Alexey Samsonov 961276af26 [Sanitizer] Extend a symbolizer code. Implemented for Linux only. Use dl_iterate_phdr to get virtual addresses of mapped module sections. To symbolize an address from a module, map this module to memory and obtain pointers to debug info sections. Later these pointers can be passed to constructor of DWARF context-in-memory from LLVM DebugInfo lib.

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
