It took some fighting with tcl syntax until I arrived at the regex
pattern below but it looks like it is possible.

 "vect_recog_dot_prod_pattern: detected(?:(?!failed).)*succeeded".

This seems to work for the failing cases and I'm going to send a patch
tomorrow if an x86 testsuite run is unchanged.
