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.

dd9be4ef58 Matching a back-reference must handle unbound start-register (but can assume that if start register is bound, then end register is bound too). 
After matching a back reference, the character position is advanced past
the match

5c39d9c741 Added checking in the regular expression parser that we're below the 
stack limit and that the zone allocation limit hasn't been met.

49d05495d8 * Remove an unused layer of abstraction by not having both a macro assembler and 
an assembler when compiling to bytecode.  This fixes
  http://code.google.com/p/v8/issues/detail?id=165
* Preload the 'current character' register when starting a match (byte code only
  at the moment).

144c8c790a Fixed problem where the two lower-case sigmas would uncanonicalize to 
themselves and upper-case sigma, but upper-case sigma would
uncanonicalize to just lower-case final sigma.
