Update (add back) a few known crash to list.

chrome/test/data/reliability/known_crashes.txt

 # This file contains known patterns of crash signatures. One pattern per line.
 #
 # A crash signature is the concatenation of the top N functions, delimited by
 # '___', in chrome.dll on the crash stack. All characters are lower case.
 #
 # We use crash signature patterns as our list of known crashes. A crash
 # signature pattern is a string that can be used to identify a known crash. We
 # use the notion of patterns because crashes with the same root cause can often
 # differ somewhat in their crash stacks. A pattern is intended to be a
 # generalized, yet still identifying, form of a particular crash. Usually a
 # pattern will contain part of a crash signature, for example a prefix, but it
 # can be more sophisticated, such as a regular expression. See below for more
 # details.
 #
 # The format of known crashes in this file is as follows:
 #   TYPE : PATTERN
 #
 # PATTERN: A crash signature pattern is a potentially identifying string that
 #          can be used to match a crash signature.
 # TYPE: The type of the pattern, indicates how the pattern should be matched
 #       against crash signatures. Possible options are:
 #           PREFIX: Match any signature beginning with this pattern.
 #           SUBSTRING: Match any signature containing this pattern.
 #           REGEX: Use this pattern as a regex to match against signatures.
 #       If the type is not listed, it defaults to PREFIX.
 
 # Any crash due to out of memory is ignored.

 # Mysterious crashes. Leave them for now.
 
 # It is too broad to exclude all purecall related crashes. Thus here we filter
 # any purecall crash immediately after runtask.
