876e23c54d [regexp] Fix incorrect DCHECK in FixSingleCharacterDisjunctions 
The condition only applies in unicode mode, where any lone surrogates
are desugared into a character class (and will not be considered in this
optimization). Non-unicode mode treats lone surrogates exactly like
any other codepoint.

e29fcbee9c [regexp] Move RegExp.prototype[@@search] to TF 
Implements upcoming changes to @@search according to
https://github.com/tc39/ecma262/pull/627.

33a4faa47d [regexp] Port RegExp.prototype[@@replace] 
This moves the implementation of @@replace from regexp.js to builtins-regexp.cc
(the TurboFan fast path) and runtime-regexp.cc (slow path). The fast path
handles all cases in which the regexp itself is an unmodified JSRegExp
instance, the given 'replace' argument is not callable and does not contain any
'$' characters (i.e. we are doing a string replacement).

7aec228dbb Cleanup of mjsunit.js code and make assertEquals more strict. 
Encapsulate the helper functions in mjsunit.js.
Now only exposes the exception class and the assertXXX functions.

Make assertEquals use === instead of ==.
This prevents a lot of possiblefalse positives in tests, and avoids
having to do assertTrue(expected === actual) when you need it.

Fixed some tests that were either buggy or assuming == test.

6e13e8ce37 Parsing a RegExp decimal escape could overflow, making an otherwise too large 
decimal escape be accepted as a capture index.
We introduce a limit on the nubmer of allowed captures in a regexp, and break off
parsing of the decimal escape at that point.

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

6bd6376588 RegExp parser forgot to advance after reading \c in character class. I.e., \cM was interpreted as \ccM.

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.

c42f5829a1 Included mjsunit JavaScript test suite and C++ unit tests. 
In the shell sample don't print the result of executing a script, only
evaluating expressions.

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.
