[ASan] Small fix to please tests on Windows, where stack unwinding using provided pc/bp works too bad

Otherwise Clang eliminates everything after the first interface symbol that is marked noreturn.

[ASan] Create new files asan_report.{h,cc} as a preparation for refactoring of ASan error reporting code.
Currently ASan reports many kinds of errors, and the code that actually prints error messages can
be found inside allocator, OS-specific files, interceptors code etc.

An example of maintenance troubles this situation causes:
There is currently an ASan interface function that registers
callback which should take the char buffer with error report printed by ASan.
This function is now broken, as one has to insert callback calls to all the places in
ASan code where the error reports are printed, surprisingly it is not only
"__asan_report_error" function...

AllocationSize(ptr) should check that |ptr| actually points to the beginning of the chunk it belongs to.

Some refactoring for asan_symbolize.py: introduced the Symbolizer class and implemented DarwinSymbolizer for atos-based symbolization, BreakpadSymbolizer for breakpad-based symbolization (files produced by the dump_syms tool, http://code.google.com/p/google-breakpad/source/browse/#svn%2Ftrunk%2Fsrc%2Ftools%2Fmac%2Fdump_syms) and ChainSymbolizer to allow falling back if a symbolizer hadn't succeeded.
Fixed pylint warnings.

[Sanitizer] Workaround for a compiler warning - ISO C++ forbids casting pointer-to-function to pointer-to-object, so we use cast via integral type

llvm-svn: 161168

Make strcat() and strncat() more standard-compliant (check for invalid parameters even if zero bytes is copied, more accurate overlap check)
Fix the tests that were relying on the incorrect behavior.

Add support for "movsbl %sil,%ecx" (x86_64) and "movsbl $imm(%ebp), %edx" (i386) to our fork of mach_override.

[ASan] cleanup interceptors code - prefer ASAN_INTERCEPT_FUNCTION_NAME macro to _WIN32, __APPLE__ etc.

llvm-svn: 161109

First tiny move towards integrating AddressSanitizer regressions test into LLVM lit-based testing infrastructure.
The goal is to be able to run ASan tests by simply running "make check-asan" command from CMake build tree:
* tests should use fresh clang binary from current build tree.
* tests should use the same RUN-lines syntax as llvm/clang reg tests.

Next steps:
- restricting tests to machines where target is equal to host, i.e. where we can produce working binaries.
- moving AddressSanitizer unit tests to lit as well.

[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.
