Currently we search for the llvm-symbolizer binary along `$PATH`. This doesn't work very well if the LLVM binary is run from the build area, or is installed in some directory that's not on the `$PATH`. This patch changes the crash reporter to look for the symbolizer binary in directory of `argv[0]` before it searches `$PATH`; most of the changes here are wiring `argv[0]` from each of our `main` functions through to the crash reporter.
