d7c933e7ae Added support in the profiler for creating 'regions' that cover part 
of the generated code.  These can be used by the profiler to
categorize the ticks that occur within generated code and thereby show
more detailed information about where time is spent in generated code.
For instance, this is what the profiler displayed for a simple regexp
benchmark with irregexp-native before:

[JavaScript]:
   total  nonlib   name
   87.2%   87.2%   RegExp: (?:\w*\W+)*

This is what we can display now:

[JavaScript]:
   total  nonlib   name
   87.2%   87.2%   RegExp: (?:\w*\W+)*

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.

b3dd6b686a Refactored the recording of source position in the generated code. The code generator now has two methods 
void CodeForStatement(Node* node)
  void CodeForSourcePosition(int pos)

The first is used to indicate that code is about to be generated for the given statement and the second is used to indicate that code is about to be generated for the given source position.

Added position information for some statements which was missing whem.

Updated the code generator for ARM to emit source position the same way as for IA-32.

Added an assert to ensure that deferred code stubs will always have a source source position as if it has not it will take whatever source position before which makes no sense.

The passing test on ARM has only been tested using the simulator.

6297a19160 Improve mark-compact object grouping interface. 
The main goal was to improve O(n^2) behavior when there are many object groups.  The old API required the grouping to be done on the v8 side, along with a linear search.  The new interface requires the caller to do the grouping, passing V8 entire groups at a time.  This removes the group id concept on the v8 side.

  - Changed AddObjectToGroup to AddObjectGroup.
  - Removed the group id concept from the V8 side.
  - Remove a static constructor while I'm here, lazily initialize
    the object groups list.
  - Cleaned up return by non-const references to return pointers.

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.
