Rui Ueyama 647132cc23 [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.
