c89021d162 Added labelled thread names to help with some debugging activity. Right now, 
the only platform that it works on is linux (using the prctl API to set the
names of the threads). Other platforms are setup to build properly if the
flag is set, but their thread names are not currently set.

c1fd8bcf60 Fix a bug in deoptimization environments. 
The function HEnvironment::SetExpressionStackAt did not update the
environment's history.  This function is used to patch the bailout
environment for count operations and global function calls.

Reorganize class HEnvironment to make it fit V8's style a bit better
and to try to add some sanity to which C++ functions are intended to
be inlined.

Remove the flag --trace-environment which merely duplicated data in
the hydrogen.cfg file except without enough context to be useful.

0a128e5ae7 Optimize array-length and fast element loads. 
1. Separating out the instance-type check from the array-length operation.

2. I also changed the bounds-check on keyed loads to use the length property
for JS arrays (like we do for array stores).

The new pattern should use less registers and allow more checks to be eliminated.

e21d76a0e3 1. Added support for object printing for release mode using the 
objectprint=on (defaults to off) option (which defines OBJECT_PRINT).
2. Added the ability to print objects to a specified file instead of
   just stdout.
3. Added a use_verbose_printer flag (true by default) to allow some
   object printouts to be less verbose when the flag is false.
4. Fixed a bug in VSNPrintF() where it can potentially write into an
   empty char vector.

6cc0310a72 Mark map-transition stores as map-changing instructions. 
This prevents code motion from hoisting map-checks across such stores
which may result in unnecessary deoptimizations.

In the following example program we would move a map-check from the inner loop out before the outer loop which is not desirable:

function f() {
  var o = {};
  var j = 0;
  o.a = 1;
  do {
    o.b = 6;  // Map transition
    for (var i=0; i<10; i++) {
       o.a = o.b + i;
    }
  } while(++j < 1) {}
}
