118a421067 Simplify the transitions in the Binary Op ICs. Now a single call 
to the runtime will both patch in the more specialized binary op
stub and calculate the answer.  This eliminates the need to call
both the rest of the binary op and the patching runtime call.  The
runtime routines are altered to be more agressive in returning
Smis so we don't get spurious heap numbers as inputs to binary ops
while we are patching the binary op ICs.

a50e72575e JS2C tweaks: 
o Only substitute constant values for full-words and not for
   accidental partial matches.

 o Keep the order of macros as in macros.py and allow depending on the
   previous macros.  We used to allow depending on macros that
   happened to sort after the current one in the dictionary.

9added5953 Clear function breakpoints in Debug::HandleWeakDebugInfo callback.

This is needed because function will live in heap until next gc, and therefore can be found
by Runtime::FindSharedFunctionInfoInScript.

4ad3fdb1f4 Update the ES5 conformance tests to the latest version and fix test 
expectations.

We are currently using a rather old version of the ES5 conformance
tests and there has been a range of bug fixes in the test set. This
change brings us up to date. 

In addition, our current test expectations discards the all chapters
but chapter 15. I have enabled the other chapters, cleaned up the
tests that we no longer fail on, and filed bugs for tests that we fail on.

It seems some of the bugs on the es5 conformance bug-tracker has been
fixed but not marked fixed. I will file bugs for the newly discovered
test bugs.
