6fa2f4f0c9 RegExps now restart if their input string changes representation during preemption. 
Cleaned up the handling of strings moving, so strings moved by GC and strings changing representation are handled equivalently.

eb656c723b Moved subject and index before matches in RegExp lastMatchInfo. 
Some minor changes, and removed the new handlescope in the inner loop of replace. Only really affects replaces on extremely long strings.

608a99a90c Remove all uses of StringShape variables, since that has proven 
to be error-prone and of little benefit in terms of performance.

c1c5a09ebd Made the Error prototype into an error. Allow \c at the end of 
regexps.  Throw a type error when calling regexp methods on
non-regexps.

6e13e8ce37 Parsing a RegExp decimal escape could overflow, making an otherwise too large 
decimal escape be accepted as a capture index.
We introduce a limit on the nubmer of allowed captures in a regexp, and break off
parsing of the decimal escape at that point.

forgetting to run the tests before submitting!

09e3c76137 Quantified look-aheads are sometimes removed entirely, leaving only a 
single atom node. A flag was not set in this case, leading the wrapper
code to think the pattern was equal to the atom and use the pattern
in the indexOf operation.

ff3e30ae11 - Added lookbehind propagation for the initial node; now, if the 
initial node is interested in what precedes it the automaton is
  given an initial all-consuming character class that determines it.
- Added verification of some node information invariants.  We now
  check that if a node expresses interest in what precedes it that
  information is available to it after assertion expansion.

ba09ec5e89 Irregexp: 
* Facility for generating a node several ways.  This allows
  code to be generated for a node knowing where it is trying
  to match relative to the 'current position' and it allows
  code to be generated that knows where to backtrack to.  Both
  allow dramatic reductions in the amount of popping and pushing
  on the stack and the number of indirect jumps.
* Generate special backtracking for greedy quantifiers on
  constant-length atoms.  This allows .* to run in constant
  space relative to input string size.
* When we are checking a long sequence of characters or character
  classes in the input then we do them right to left and only the
  first (rightmost) needs to check for end-of-string.
* Record the pattern in the profile instead of just <CompiledRegExp>
* Nodes no longer contain an on_failure_ node.  This was only used
  for lookaheads and they are now handled with a choice node instead.

an assembler when compiling to bytecode.  This fixes
