c093e94546 - Pass the knowledge whether the old GC is compacting to the GC prologue and epilogue. This allows us to skip frame cooking and uncooking when doing a mark-sweep GC. 
- Add the ability for the code to refer to its code object by adding a handle to the code object in the MacroAssembler.

cf1e1b1b98 Trace contains information about whether we know that we are at the start of input. 
Choice nodes may know that they are never not at the start of input.
This can remove start_of_input assertions in cases where they are statically known to fail.
The initial loop is unrolled once if the regexp might check for the start of input. Only the first iteration may be at the start, the following loop knows that it isn't.

them to restore state.

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.
