[git-llvm] Check if svn is installed. The error message that git-llvm script prints out when svn is missing is very cryptic. I spent a fair amount of time to find what was wrong with my environment. It looks like many newcomers also exprienced a hard time to submit their first patches due to this error. This patch adds a more user-friendly error message.
