Alexey Samsonov 419f610a74 [Sanitizer] Switch the symbolization strategy that would be used by sanitizer tools family: as compiling in-process symbolizer into runtime involves certain difficulties, we may instead launch an external symbolizer program (fork + execl) in a subprocess and communicate with it via pipe.

Alexey Samsonov 500e99639d [Sanitizer] Wrapper around llvm::DIContext from LLVM DebugInfo library. If a macro SANITIZER_USES_LLVM_LIBS is defined (by default it is not), then sanitizer runtime includes llvm headers and tries to use LLVM libs for in-process symbolization. To make it functional, we have to link with these LLVM libs - either pass them to linker from Clang driver, or link them into static ASan runtime when we build it.

Alexey Samsonov 7acdc1738f [Sanitizer] When obtaining the data for loaded modules, add address ranges of loadable segments only. Looks like address range of PT_TLS segment may intersect with loadable segments of other modules.

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 3a6ddb86e8 [Sanitizer] Allocator for internal runtime purposes. Currently it calls libcmalloc, but we might have to make it more low-level in future

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
