Right now iOS 6 and iOS 7 using the Remote Inspector won't show source maps with data URLs even though they could.
SourceMapResource#sourceMapResourceLoadError will need to not throw an error, or be otherwise avoided when using the remote inspector on iOS 6 or 7, or else execution will stop.
When possible, we should title radars based on their user impact, instead of the code change. The _loadAndParseSourceMap part is overly specific, in case this were to change.

This is no longer a concern. An error is no longer thrown.
What needs done here?

SourceMapManager only loads SourceMap resources if NetworkAgent.loadResource exists (so it can load the resource through the inspected page). If that doesn't exist (e.g. iOS 6 and 7) we don't even try to load source maps.
I'm not sure if it is worth the time investment at this point to implement something for iOS 6 and 7 here. I believe we used to do an XHR / synchronous load from the frontend, which won't work in all cases anyway.
