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

[asan,tsan] introduce sanitizer_common/sanitizer_defs.h and perform some renaming in asan rt. More to come.

It turns out that atos does not print the symbol names for static C++ functions correctly (one of the two leading underscores is omitted), so they remain mangled.

which will contain code shared between asan and tsan run-times.

Naming is hard. If you can suggest a better name for the directory -- speak up.

Clients may define the __asan_default_options char string containing the default options for the tool now.

Add support for the GCOV_PREFIX_STRIP env variable which tries to strip off the first 'n' directories from the filename.

we can't open the file even after creating all of the directories to it, then
just give up.

* Check for absolute paths before using the GCOV_PREFIX.
* Don't add an ending path separator if there's already one.

When the flag is set to zero, we do not check for errors in malloc_usable_size.
This may be useful to work around a bug in Nvidia drivers prior to 295.*
