            Bug ID: 17060
           Summary: [ASan RTL] Make llvm-symbolizer the default
           Product: compiler-rt
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: compiler-rt

The user experience of ASan is tremendously better when using llvm-symbolizer.
Let's make it the default.

Two suggested ways to make it the default:

1) embed the path to llvm-symbolizer at link time by looking relative to the
clang driver

2) look in PATH

If we find an executable llvm-symbolizer in either place, use it. If not,
fallback. This should still be overriden by the ASAN_SYMBOLIZER_PATH
environment variable.
