356cf1ed0a RegExp: Add support for table-based character class
code generation.  This is performance neutral for
all our tests, but a factor 6 faster for the Unicode
based regexp in the new test (and much more compact
code).

30a0a7de43 Split nested namespaces declaration in two lines in accordance with C++ Style Guide.
This issue was raised by Brett Wilson while reviewing my changelist for readability. Craig Silverstein (one of C++ SG maintainers) confirmed that we should declare one namespace per line. Our way of namespaces closing seems not violating style guides (there is no clear agreement on it), so I left it intact.

263bac505b * Irregexp: Move from a byte-oriented bytecode format to a 32-bit oriented
bytecode format.  This provides a nice speedup on Intel and probably an
even better one on ARM.  Also removes the 256-register limitation on the
interpreter.

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.
