Make Script.prototype.nameOrSourceURL use indexOf search first before trying to match with a RegExp.

Make Script.prototype.nameOrSourceURL use indexOf search first before trying to match with a RegExp.

This should use Boyer-Moore search with a long string, which is potentially
faster than RegExp search.
The target string is typically, but not guaranteed, at the end of the
source, so for long sources, there will be a lot of characters to skip.
