[Ironruby-core] Code Review: StringGsubWithStringPatternAndBlock

Comment  :
  This change fixes the rest of the gsub coverage minus one (String#gsub with pattern and block raises a RuntimeError if the string is modified while substituting).  We had a similar issue implementing squeeze so it looks like we will have to track inflight changes to the underlying string (frozen already does this, I wonder if there is some variant we can use).

  This changes fixes the following specs:

  String#gsub with pattern and block sets $~ for access from the block
  String#gsub with pattern and block restores $~ after leaving the block
  String#gsub with pattern and block sets $~ to MatchData of last match and nil when there's none for access from outside
