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.

* 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.

- Added caching of regexp data in the compilation cache.

- Changed the structure of regexp objects from having two internal
fields to having a single field containing a fixed array, since it's
easier to store the whole fixed array in the cache.
- Move printing of the command to after printing std{err,out} in the
compact progress indicators in the test framework.

If an allocation is so huge that we cannot code the size needed in the failure
...
object then we just return an out of memory failure object (instead of a retry
after GC failure object). Not all places that checked for retry-after-GC were
able to handle an immediate out of memory failure.

underlying string representation of the two strings involved.
- Renamed ascii and two byte string classes to sequential ascii and
sequential two byte, and renamed IsAscii and friends to
IsAsciiRepresentation. This is to make a clear distinction between
strings with an ascii/two-byte representation, of which there is
four, and flat sequential ascii/two-byte string.

In the shell sample don't print the result of executing a script, only

Fixed issue when building samples on Windows using a shared V8
library. Added visibility option on Linux build which makes the
generated library 18% smaller.
Changed build system to accept multiple build modes in one build and
generate seperate objects, libraries and executables for each mode.
Removed deferred negation optimization (a * -b => -(a * b)) since this
visibly changes operand conversion order.
Improved parsing performance by introducing stack guard in preparsing.
Without a stack guard preparsing always bails out with stack overflow.
