Update static_initializers tool to build easier, find more

static_initializers failed to find the initializer/destructor code for
g_fallback_crash_handler_launcher because it was of this form:
    `dynamic atexit destructor for '

So, this pattern is now watched for. This change also adds a build.bat
file and .gitignore file. If we add this to the bots we'll need to make
it part of the .gn build.
