[RFC] Speeding up delta by -fatal-errors

[Richard Guenther]

Hi!

To speed up automatically reducing testcases with delta we don't
currently have something like -fatal-errors which exit on the first
error occoured, but we rather keep going.  So would something along
the simple approach below be acceptable?  (Plus adding the -fatal-errors
switch and documentation, of course)  Any better ideas?  Do we even have
something like this already?

Thanks,

Richard.
