[PATCH] Support for separate debug info files in asan symbolize script

[Alexey Samsonov]

Why can't you use llvm-symbolizer? This tool implements searching for separate debug info files (looking at /usr/lib/debug, calculating crc32 hashes and so on). I was sure that addr2line does this as well. This should be the responsibility of the tools we invoke through asan_symbolize.py script, not the script itself.
