[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.

[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.

[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.

[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.

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
