[Sanitizer] Use __libc_malloc/__libc_free instead of malloc/free inside internal allocator on Linux (important for TSan)

llvm-svn: 158261

llvm-svn: 158202

[Sanitizer] move internal_strdup and internal_memcpy to common runtime. Make internal allocations from TSan runtime call InternalAlloc from common runtime

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

[Sanitizer] Use common CHECK machinery. Currently each tool has to define its own CheckFailed function.

[Sanitizer]: Introduce a common internal printf function. For now, also use tool-specific wrappers TsanPrintf (its output is controlled by TSan flags) and AsanPrintf (which copies its results to the ASan-private buffer). Supported formats: %[z]{d,u,x}, %s, %p. Re-write all format strings in TSan according to this format (this should have no effect on 64-bit platforms).

[Sanitizer] add sanitizer_common.h for routines shared between TSan and ASan runtimes. Use __sanitizer::Die() in TSan.

[Sanitizer] Use common defines for ASan and TSan runtime. Split defines between interface defines (can be visible in user code that includes interface ASan/TSan headers) and internal defines.

[Sanitizer] add sanitizer_posix.cc. Move more various functions into sanitizer_libc: sscanf, munmap, memchr

[Sanitizer] Add sanitizer_win.cc for windows-specific implementations of libc functions. Add internal_open.

llvm-svn: 157985

llvm-svn: 157931

Created files sanitizer_linux.cc and sanitizer_mac.cc for platform-specific implementations of common functions. Turned asan_mmap into __sanitizer::internal_mmap.

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.
