0b1f3f2134 Issue 231 - Irregexp backtracking stack pointer could become corrupted. 
http://code.google.com/p/v8/issues/detail?id=231

2de5de495f Irregexp: Backtrack past look-aheads works correctly. 
Allows backtracking to clear registers instead of pushing and popping
them to restore state.
Redo of 1135 with bug fixed.

c956219ef4 * Remember to check for end of string even where we 
know the character class must match.
Thanks to Mads and Christian for finding this bug

18c2d3ef4e Clears captures of look-aheads on backtrack. 
Reduces number of pushes when flushing a trace. Some are converted to clears
in the undo-code instead, and some just ignored if they have no value worth restoring.

ab2d4bc9bf * Generate quick checks based on mask and compare for 
the alternatives in a choice node.  The quick checks
  are conservative in the sense that they only detect
  failure with certainty.  Checks can do 2 or 4 characters
  at a time.
* Inline the quick checks to allow the alternatives to
  be checked without branching in the common case where
  they fail.

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.
